1In many African societies, children belong to a lineage and not to a couple, and may circulate between different members of the extended family (Lallemand, 1993). Under this system, children may be temporarily fostered, or given away permanently through adoption (Bledsoe, 1990; Castle, 1995; Etienne, 1979; Goody, 1982; Jonckers, 1997; Lallemand, 1988, 1993; Madhavan, 2004; Rabain, 1979). These practices are intended to create or strengthen mutual support and kinship ties within a social and familial mode of organization based on the principle that burdens must be shared across the entire family network (Antoine et al., 1995; Marie, 1997; Oppong, 1999; Pilon and Vignikin, 2006). While children frequently move around between relatives, both temporarily and permanently, such movements are much rarer outside the family circle.
2However, this practice of child transfers for purposes of social exchange is becoming more diversified today. For several decades now, children have been fostered out to urban families in exchange for some domestic duties so that they can attend school (Jonckers, 1997; Vandermeersch, 2002). In a context of rural poverty, families are now less reluctant for their children to move to town to find work, or even encourage them to do so. Such practices are becoming increasingly widespread, and when the farming calendar so permits, a growing number of rural adolescents, at ever younger ages, now set off to look for an additional source of income (Delaunay et al., 2006; Erulkar et al., 2006). Children and adolescents who move to another household, on their own initiative or otherwise, may be exposed to various forms of discrimination (access to health care, food, education) and exploitation (labour, violence, including sexual violence).
3Children generally enter the labour market via family networks. These networks are increasingly structured and organized, with limited family control (Jacquemin, 2009), and the risks of child exploitation are considerable. These aspects deserve fuller investigation. A study of young maids in Côte d’Ivoire identified various forms of child labour placement (Jacquemin, 2009). The first is an extension of the practice of child transfers; children are placed with relatives so that the family of origin has one less mouth to feed while the host family acquires an extra pair of hands in exchange for food, lodgings, health care and possibly education (“little nieces”). The second form involves the family network, in the sense that the child is placed by a relative acting as “tutor”, but in a non-kin household, in exchange for a small wage that is managed by the tutor (“rented child”). The third and most recent form involves intermediaries outside the family network (placement agencies, acquaintances). In such cases, the child is considered as a worker and receives a wage directly from the employer. These children, often referred to as “little maids”, are generally older. Similar situations are described in other countries, including Senegal (Delaunay and Enel, 2009) and Mali (Lesclingand, 2004).
4The issue of child labour has prompted intense concern over the last decade (Bonnet and Schlemmer, 2009; Invernizzi, 2003; White, 1996), and international directives have been issued to identify and eliminate the “worst forms of child labour”, including types of work that are “likely to harm the health, safety or morals of children” (International Labour Organization, Convention no. 182).
5This article proposes an indirect measure of situations of child labour based on Demographic and Health Survey (DHS) data. While these surveys do not include information on employment, they provide data on children’s residential situations. The measure proposed here is based on the postulate that a school-aged child living with non-relatives and not attending school is engaged in child labour. If this postulate is verified, it becomes possible to measure child labour indirectly in many countries and at different times.
6In the case of Madagascar, child fosterage is limited to the circle of close relatives (Dahl, 2006). The rules of mutual assistance apply solely within the family, and it is very unusual for a household to take in a child who is not a relative. So the postulate appears to be confirmed. But we also know that many Madagascan children have jobs, including within the family, and that even those who attend school may work outside school hours (Rakoto-Tiana, 2011b). The proposed indirect measure will thus inevitably underestimate the scale of the phenomenon.
7Our aim here is to test the validity of this estimation method – which has the advantage of using data that already exist and are available in many countries – and to test its usefulness in understanding the determinants of child labour.
I – Child labour in Madagascar
8The most recent census in Madagascar dates back to 1993, at which time the specific occupation rate [1] was 27.1% for all children aged 10-14, with a higher rate in rural areas (31.8%) than in urban areas (11.4%). Boys were mostly employed in agriculture (90%), with a small percentage in domestic work (4.1%). Girls also worked on the land (78%), but a larger proportion were in domestic service, notably in the towns and cities (17.2%) (Institut national de la statistique, 1997).
9A more recent survey on child labour in Madagascar (Institut national de la statistique, 2008) has produced statistical data on the employment situation of children in households. It shows that 28% of children aged 5-17 were in employment at the time of the survey, especially in rural areas (31% versus 19% in towns). The share of economically active children increases with age, from 13% at ages 5-9, to 32% at ages 10-14 and 55% at ages 15-17, with a slightly higher rate for boys than for girls (30% versus 27%). [2] More than half of all working children are employed in farming and fishing (69% of working boys and 48% of working girls), and two-thirds have the status of domestic helper. A very high proportion (87%) do work that is considered harmful [3] (Institut national de la statistique, 2008).
10One of the conclusions of this study is that “living with one’s biological parents is a precious advantage for child protection” (Institut national de la statistique, 2008). Children who live elsewhere are more likely to engage in harmful economic activities or to be exploited. These findings are less clear-cut in the most disadvantaged populations of Antananarivo, where a study of child beggars showed that the vast majority actually do live with their parents (Ballet et al., 2010).
11An analysis of fostered children showed that 39% are fostered so that they can attend school. However, 12% were not in school at the time of the survey (Ballet et al., 2011), perhaps because they had performed poorly in school, or perhaps because they were prevented from attending by the host family. In group interviews with social workers involved in looking for lost children in Antananarivo, frequent cases were mentioned of children fostered to relatives so that they could attend school but who were exploited by their foster family and ended up running away (Bhukuth and Ballet, 2009).
Research framework and hypothesis
12Children are considered to be in a situation of child labour if the three following conditions are satisfied: they do not live with either of their parents; they live in a household headed by a person who is not a relative; they do not attend school.
13The Demographic and Health Survey (DHS) provides representative national data that can be used to identify children who are fostered or placed. Children living in a household without their parents can be identified, along with their relationship to the household head. Children living with non-relatives and not attending school are considered to be in a situation of child labour. For this reason, the analyses focus on children aged 6-17, ages at which children normally attend school.
14The proportion of children engaged in child labour at national and regional levels can thus be calculated. It is also possible to calculate this proportion for sub-groups defined according to the household’s socioeconomic status, the educational level of the household head, or the place of residence (urban/rural), and hence to estimate the prevalence of child labour by selected characteristics.
15The hypotheses tested here concern the existence of different models of child labour among children placed with non-relatives. These models appear to differ by sex. Demand for farm labour, concentrated in certain zones of the Central Highlands (rice growing and livestock breeding), and greater demand for domestic workers in urban areas suggest that placement models are geographically oriented towards active rural areas and towards towns and cities.
II – Method
16The data used are those of the 2008-2009 Demographic and Health Survey conducted on a sample of 17,857 households. [4] Only de jure residents are considered, i.e. habitual members of the household, excluding persons who simply spent the night preceding the survey in the household (de facto residents).
17The survey recorded family relationships, and the response categories included “fostered or adopted child”. We did not use this information as it is incomplete and often unreliable. For example, a fostered child can also be the nephew of the household head, in which case the interviewer can either record him as a nephew or as a fostered child. We therefore preferred to define a fostered child in terms of the presence or absence of his or her parents in the household. Household members are analysed using a method developed by Christine Tichit to define household structures (Tichit, 2009). Under this method, children living in a household without their father or mother (including orphans) are considered as fostered.
18Our study concerns a total of 43,727 de jure residents aged 6-17, excluding married children, parents or household heads.
19The analysis focuses both on fostered children and on children engaged in child labour, measuring their prevalence by certain characteristics relating to their place of residence, their parents’ vital status, the characteristics of the household head and of the household of residence.
III – Results
Fostered children
20By analysing the children’s situation in terms of the parents’ presence in the household, it is possible to distinguish between children of the household’s principal nucleus (children of the household head or of his/her spouse), and children of other adults in the household (secondary nucleus) or children whose parents are not resident in the household. It is these last children who form the “fostered” category.
21There are 5,912 fostered children in our sample, i.e. 13.5% of the total. The proportion is low for very young children and increases with age: 7.7% at ages 0-5, 11.5% at ages 6-9, 18.8% at ages 10-14 and 22.5% at ages 15-17 (Table 1).

* The principal nucleus is that of the household head; the secondary nuclei are those of other adults in the household (husband/wife couples or parent(s)/child(ren)).22The fostered children category can be sub-divided by relationship with the household head. More than half of all fostered children – and more than 80% of those aged 0-4 – live with their grandparents (Table 2). They are generally young, with a mean age of 8.6 years. This finding attests to the role played by grandparents in raising small children (Andiamaro, 2013; Dahl, 2006; Delaunay et al., 2010). The proportion decreases with age, down to 26.5% at ages 15-17, as the grandparents grow older and their mortality increases.

23Around 15% of fostered children live with an uncle or aunt, with a proportion ranging from 9% for the youngest children to 18% for the older ones. It seems that maternal uncles and aunts play an important role in child care, in certain social groups at least (Goedefroit, 1998), and represent an alternative to parental care, whatever the child’s age (Dahl, 2006 ; Rakotonarivo, 2010). In Madagascar, it is not unusual for a young person with a job to support and care for a younger sibling (Dahl, 2006), and 9% of fostered children live with a brother or sister, most often after reaching school age. A further 8% of fostered children live with another relative, with a proportion ranging from 3% for the youngest to 17% for the oldest. Note that this type of fosterage may be for reasons of schooling, or for employment as a domestic helper.
24Last, 11% of fostered children live with a person who is not a relative. The proportion ranges by age from 4% to 22% and represents 666 children in total. [5] Here too, children may be fostered for reasons of schooling or employment as a domestic helper, although the rules of solidarity with regard to schooling rarely extend beyond the family circle (Rakoto-Tiana, 2011a).
25For each child, the survey provides information on their school attendance during the year in which the survey was conducted. We sorted the fostered children by place of residence and school attendance (Table 3). Information is missing for 31 children. The highest proportion of fostered children not attending school are those living with a non-relative (61%), and the percentage is also high among those living with an “other relative” (45%). Children aged 6 and above who live with a grandparent, an uncle/aunt or a sibling more often attend school (73%, 67% and 74%, respectively), confirming that in these cases fosterage is most often for schooling purposes.

26The DHS sample thus provides us with 384 cases corresponding to our definition of children engaged in child labour (child not living with parents, residing with a non-relative, aged 6 or above and not enrolled in school).
Children engaged in child labour
27Some 1.4% of all children aged 6-17 in the sample are potentially engaged in child labour (Table 4), a proportion that is low but not negligible. It corresponds to a possible national total of 100,000 working children. [6]
28There is no distinction by sex (1.4% for boys and 1.3% for girls), but gender differences appear when place of residence and region are taken into account. Female child labour is more prevalent in the capital, Antananarivo (4,6 %), and in other cities (2,5 %), while for boys the prevalence varies little between urban and rural areas. Female child labour tends to be an urban phenomenon which corresponds to the employment of girls as domestic helpers.
29The prevalence by region reflects these findings: it is higher in Analamanga and Atsinana, the regions where Madagascar’s two largest cities, Antananarivo and Toamasina (Tamatave), are located. The highest prevalences of male child labour are found in the regions of Alaotra Mangoro, Itasy, Betsiboka and Bongolava. The first three are major rice-growing regions, notably Alaotra Mangoro, known as Madagascar’s rice granary, while Bongolava is a region of intensive livestock production. Male child labour appears to be primarily concentrated in farming.
30Prevalences by characteristic show some variations. They increase with age (3.9% at ages 15-17), are higher among orphans (or children whose parents’ vital status is unknown, 11.0%), in households whose head is educated (4.3% when the head has secondary education or higher), in wealthier households (3.5%), in childless households (5%) and in complex households (3.1% for boys) (Table 4).

31A logistic regression (Table 5) confirms these relations and distinguishes the male and female models more clearly. The children at highest risk are those aged 11-14 and 15-17 with a parent who is deceased or whose vital status is unknown. The male model is characterized by a much higher risk of child labour in rural areas, while for girls the risk is higher in the capital and in the countryside than in small towns. The risk increases considerably with the educational level of the household head, and is especially high in the richest households, for both boys and girls; it is low in lone-parent households.

Boys in rural areas are 3 times more likely to live with non-relatives and not attend school than boys in the capital.Significance levels: *** p 0.01; ** p 0.05; * p 0.1; ns: non-significant.
IV – Discussion
Indicator quality
32Estimates of the prevalence of child labour are based on a definition that is plausible but needs to be discussed. Children are considered to be engaged in child labour if they live with a non-relative without their parents and are not enrolled in school. This category may include children who are adopted and who, like the adoptive family’s biological children, cannot afford to attend school, but who are not necessarily exploited. This would lead to an overestimation of children engaged in child labour whose amplitude is difficult to determine, but which, in the context of Madagascar where non-family adoption is rare (Dahl, 2006), is likely to be small. Moreover, attending school does not protect against economic exploitation, and many school-children also work outside school hours (Rakoto-Tiana, 2011b). This suggests that the estimated prevalence of child labour obtained with our indicator is actually below the true level.
33Moreover, certain testimonies (Bhukuth and Ballet, 2009) suggest that children living with distant relatives (“other relative”) are also at risk of economic exploitation. Indeed, there may be a tendency to report a child maid as a distant relative in order to avoid any suspicion in this respect. This category was not included in our analyses. It is clear that our measures are underestimated and represent minimum prevalences at best. They can be compared with those obtained by the ENTE child labour survey (Enquête nationale sur le travail des enfants), which obtained a prevalence of 4.5% for child trafficking victims versus 1.4% for children engaged in child labour in our study (Bhukuth and Ballet, 2009). This gives further grounds for believing that our findings are underestimated.
Main findings
34Child labour mainly concerns children aged 11 and above. The educational level of the household head appears to be an important factor, for girls especially; these households have fewer children (they are the groups with the lowest fertility) and their female members are more often in employment, so their demand for domestic child labour is high. Level of wealth also appears to be a factor in demand for labour, both domestic and agricultural. Non-family child workers in farming or domestic service provide a replacement for children who are unborn, absent or deceased. These findings are consistent with a study performed in a rural area which shows that the fewer the children under age 14 in a household, the more likely it is to include a fostered child (Rakoto-Tiana, 2011a).
35We have seen that the prevalence of child labour varies by place of residence and region, and that the pattern of variation is different for boys and girls. The highest prevalences are found in the Central Highland regions, which are also the richest regions with the strongest demand for farming and domestic labour.
36This reveals patterns of placement that differ by sex. Girls tend to be placed in socially advantaged urban households to work as maids, while boys are placed both in the cities but also in rural areas with strong demand for farm labour. They are also found in the capital, and the types of work performed by boys are probably very varied. These hypotheses need to be confirmed, however.
37It is difficult to determine the extent to which these situations are harmful to the children concerned. Half of the children engaged in child labour are aged 15-17. The data gives no indication of the type of work they do. If they enjoy decent wages and working conditions, these adolescents may be better off than in their household of origin. The 10-14 age group is of greater concern. At these ages, children are growing fast, and they have little power to negotiate their wages or working conditions. It is these children who should receive the closest attention, as they are probably the group most exposed to the risk of exploitation.
38These results can be compared with those of the ENTE survey which show that children not living with either parent are more frequently employed in jobs considered as harmful (Institut national de la statistique, 2008).
39This method has the advantage of being applicable to other contexts where households provide homes to unrelated children not through altruism, but rather as a source of labour. Many countries have data from DHS or household surveys that can be used to identify children living away from their family. Here, the relationship of the children to the head of household is a crucial item of information that deserves to be recorded more fully in the DHS surveys.
Recommendations for data collection and analysis
40Further to our analyses, we would like to make a number of recommendations. The first are of a methodological nature and concern improvements in DHS data. The second are scientific and concern potential new avenues of research.
41In the DHS surveys, it would be preferable to separate the “relationship to head of household” question from the “adopted/fostered child” question, so that the mechanisms whereby a child is taken into the household can be studied. Children generally tend to be recorded as adopted/fostered when they do not correspond to any other category, i.e. when they are not related to the household head. But this may lead to confusion. It would be more useful to ask a specific question about each child, to determine whether they are either adopted or fostered, distinguishing clearly between the two categories. A child adopted by the household head is often reported as a “son/daughter”. Adopted children are thus more likely to be identified if a specific question is asked. This is especially true in Madagascar, where many child adoptions are invisible in surveys. A second methodological suggestion concerns the need to identify in surveys those children who do not live with their parents but in the household of a non-relative, so that information on the household of origin can be collected (place of residence, socioeconomic status, household structure), along with the reasons why the child is fostered.
42Regarding potential avenues of research, we believe it is very important to characterize the different types of occupation held by children and to identify those most harmful to them. According to a recent study, employment as a maid in a household of non-relatives is a key factor of vulnerability among migrants to the city: “the poorest and most vulnerable female migrants in Antananarivo (including prostitutes, garbage collectors and beggars) are those who report having been employed as maids” (Freeman et al., 2010, pp. 30-31). Likewise, we have little information on children’s participation in farm labour. Certain types of farming jobs are not necessarily harmful to children. It is important to describe more fully the types of activity and the conditions of the informal contracts binding children and their families (debt repayment, wage paid to the child or a third party, provision of food, etc.). Qualitative studies are needed to shed light on these situations and to provide pointers for the implementation of awareness, prevention and protection initiatives.
43It is equally important to understand the processes that cause children to engage in harmful types of employment, the circumstances leading to child placement, the resources and the actors involved. The causes of placement are linked to the family situation. Placement may be the result of family crisis (death, separation) or economic hardship (job loss, poor harvest, debt) which oblige the family to send the child away to work. Children may also leave on their own initiative, to escape a violent relative or spouse for example.
44The type of placement and the conditions in which children find themselves depend on the way the placement is organized. The formalization of placement networks via agencies which actively solicit rural families is an issue of growing concern.
45Last, it is important to examine how child labour affects the outcomes of these children, who are often placed in harmful employment at very young ages. Employers who use children see them as a cheap and malleable source of labour. As they grow up and become less pliant, they are replaced by younger new recruits. It is important to understand what happens to these children, whether they maintain links with their families or are drawn into other harmful labour networks for which older workers are needed, such as prostitution or modern slavery abroad…

Under decree no. 2007-563 relative to child labour, this concept refers to all types of labour by children aged under 18 that must be abolished in accordance with the national texts governing the labour market and international labour conventions. It includes the worst forms of labour: immoral labour (sex, alcohol), labour beyond the child’s physical strength, forced labour, dangerous or unhealthy labour, all work performed by children aged below 15 without the authorization of a labour inspector (Institut national de la statistique, 2008).

Of the 666 children fostered to a non-relative, 157 are coded as “adopted/fostered” in the question on relationship to head of household. It is therefore impossible to know whether the child has any kin relationship with the household head. The data would be more precise if the status of the adopted or fostered child was entered separately from the relationship with head of household so that a distinction could be made between temporary and permanent fosterage.
