Policy Brief #2:
Child poverty in Nepal

A machine learning approach

EcoLab (MoF)

2024-05-27

Background

  1. What did the recent NLSS (2022/23) reveal?

    • At the household level estimated poverty rate of \(20.22\%\) at new NLSS poverty line of NPR 72,908 per capita per year. (NSO 2024)
  2. Larger households and families with more children below 6 are significantly at higher risk of poverty.

  3. Lost opportunity to reveal any information about children living in poverty. Child poverty poses a serious threat to children [Engle and Black (2008)](Lancet 2023) as well as Nepal’s vision of an inclusive, equitable society with improved human capital and productivity (16th Plan approach paper).

  4. Urgency to fill the knowledge gap regarding child poverty as SDG 1 calls for an end to poverty in all its forms including child poverty.

Objectives

  1. Using machine learning applied to UNICEF CFT data (Aug 2023) to estimate household monthly incomes from reported household income. Estimate per capita income by using demographic structure of households.
  2. Estimate the percent of children who are poor and the percent of poor who are children. Examine other multidimensional challenges faced by children in poor and non-poor households.
  3. Simulate the impact of making the U5CG universal on per capita income distribution and poverty.

This presentation is about children and the multifaceted challenges they face including income or money. The rationale is based on the paucity of research in this area. NLSS 2022/23 did not highlight the situation of children directly and neither did the MPI report, although the latter inherently uses children’s indicators in its construct. This study utilizes the reported income data from CFT 11 and leverages the power of machine learning, both supervised and unsupervised, to decipher some of the monetary and other challenges that children in Nepal face. Starting with their families, the analysis then shifts to children themselves and examines disparities among them in terms of their HH income, place of residence and province, disability status, composition of the family, whether the family is struggling for food, whether HH has health insurance, gender, age and a range of other background characteristics. Goal is to derive income-poverty among children. What percent of children are poor? What percent of the poor are children? What are the other multi-sectoral challenges children face, and how are these correlated to income and other lenses. Finally, we imagine what would happen if the child grant were made universal at different levels of benefits.

Linear models and the LASSO models were the most divergent. Can see some convergence among other models. By comparing reported and predicted HH monthly incomes, we get an idea of under-reporting. However, this is not the point of this study. We use predicted Hh incomes (from random forest model) to generate per capita incomes and poverty. The average household income was estimated at NPR \(50,750.25\).

Estimated per capita incomes & poverty

\(26\%\)OF FAMILIES WITH CHILDREN ARE ESTIMATED TO BE LIVING IN INCOME POVERTY. BUT THERE IS A WIDE VARIATION BY PROVINCE. IN THREE PROVINCES POVERTY RATES ARE HIGHER THAN \(30\%\) AND HIGHER THAN \(35\%\) in 2.

Concomitants of income poverty

Figure 4: Concomitant challenges faced by Households

This study demonstrates that households with children, particularly those in the lower income quintiles, frequently turn to debt or asset sales to manage financial strains, alongside grappling with various challenges such as accessing nutritious food.

BUT WHAT ABOUT CHILDREN?

Derive information from the household roster which contains information on every household member.

What does the CFT data tell us about children?

  1. Average age: \(9\) years old.

  2. Average education level: Class 4-5.

  3. Gender Gap: \(53\%\) boys and \(48\%\) girls.

  4. Average age of other household members: \(40\) years with \(12\) years of education.

  5. Lives in a household consisting of \(6\) family members.

  6. \(23\%\) of children are under the age of \(5\).

Age distribution of children and their families

Figure 5: The age distribution of all HH members

The data show some evidence of ‘age heaping’ (rounding off ages). There is a gender gap between boys and girls that needs further investigation.

The age and gender profile of poverty

Among all household members, those who are in the age group 12-20 years, face the highest risks of being in a household that is below the poverty line. There is a statistically significant difference between boys and girls. This is an important finding as it underscores the need to focus on gender dimensions and this age group in addition to those under the age of five. Due to demographic changes, the age profile of poverty will increasingly consist of children who are older.

Figure 6: Age and gender profile of poverty

Child income poverty

  1. \(33\%\) of children are living in households below the poverty line. For adults the estimated poverty incidence is \(31\%\) which is statistically different (less) from the poverty incidence of kids.

  2. A gender gap exists: \(35\%\)of all girls are living in houses below the poverty line compared to \(32\%\) of boys. This difference is statistically significant. Older children, especially girls (14-19) are much more likely than to be living in households below the poverty line.

  3. \(40\%\) of the poor are estimated to be children.

"Poverty exacts a devastating toll on children, impeding physical growth, hindering social and emotional development, and shortening life expectancy. It inflates infant and child mortality rates and raises the likelihood of chronic health conditions, ravaging children with preventable diseases. Moreover, poverty perpetuates achievement gaps, amplifies parent stress, and undermines parenting practices. The dire consequences of poverty extend to children's daily lives, introducing hunger, neglect, insecurity, and instability. Additionally, poverty increases the prevalence of violence experienced by children directly and witnessed within their communities, compounding the already profound challenges they face."

(Lancet 2023)

Compounding income poverty

HH level risks and challenges translate directly into challenges and risks for children. In addition to the risk of living in households below the poverty line, children also face other household risks: \(35\%\) of children are residing in households struggling for food. \(64\%\) of children were living in households without access to health insurance. \(12\%\) of children were affected by DRR hazards. Children are also affected by coping mechanisms deployed by families. Nearly half of all children (\(45\%\)) live in households that are selling households assets to cope financially and \(30\%\) are living in households that are incurring debt to cope. The disparity between children living in poor households and those that are not is striking.

HH Struggling for food 4,958 (35%) 2,576 (27%) 2,382 (52%)
HH No health insurance 8,940 (64%) 5,638 (60%) 3,302 (72%)
HH Affected by DRR hazard 1,630 (12%) 863 (9.2%) 767 (17%)
HH Selling assets 4,232 (30%) 2,151 (23%) 2,081 (45%)
HH Incurring debt 6,232 (45%) 3,398 (36%) 2,834 (61%)

Towards action: Leveraging the U5CG

  1. Coverage is geographically uneven. Some \(25\%\) of families with children under five benefit from the child grant as it is only operational in \(25\) districts benefiting a little over \(1\) million families. There are plans to expand to all districts, but progress has been slow.

  2. In addition to the uneven geographic coverage, the value of the benefit amount is NPR 532 per month (less than \(4\) USD at current exchange rates). The poverty cut off is at NPR 6076 per month. Hence a more meaningful level of the benefit is needed to intensify the impact.

  3. However, the child grant is progressive. The figure on the right shows that there are more recipients of the U5CG from lower income quintiles. The poverty incidence among families receiving the child grant is \(35\%\) compared to \(26\%\) overall. There is scope to increase expansion - only \(32\%\) of families below the poverty line and with children under the age of five, are accessing the U5CG currently.

The question of affordability

Cost of Inaction: - Nepal risks hindering its progress and future leadership by neglecting its poorest citizens and current demographic opportunities. Persisting deprivation among young children threatens the preparedness of future generations to lead Nepal forward. Missing the chance to quickly reduce poverty, particularly among families with children under five, could have long-term negative impacts.

Recent Government Measures: - In the recent past, the Government of Nepal has doubled benefit levels and expanded old-age social security coverage, incurring significant costs covered by general revenues or deficits. These measures demonstrate the government’s commitment and willingness to invest in social protection despite these costs in the past.

Cost of Action: - A study (EcoLab: Policy Brief #1) suggests universalizing the child grant and increasing the benefit level to NPR 1,215 per month is affordable, with funding achievable through projected GDP growth-driven revenue increases. Implementing these initiatives is expected to cost an additional NPR 107 billion between 2024 and 2030, which is 0.31% of FY 2023/24 GDP annually and can be covered by the annual increase in revenues projected from GDP growth.

Sustainability and Support: - Future costs of the under-five child grant are expected to decrease as fertility rates decline, making the cost to GDP ratio negligible within two decades. Additional funding can be sourced from development partners and SDG funding (for SDG1 and others) to support capacity development and policy implementation. Seeking voluntary tax deductible contributions from upper income families and others as well as increasing the tax base are other options.

Food for thought

  1. This study has used machine learning and unveiled significant findings regarding child poverty and the various multidimensional challenges children face. The data indicate that children are exposed to numerous risks stemming from household income and other vulnerabilities their families might encounter.

  2. The analysis underscores the urgent need to accelerate progress toward Sustainable Development Goal 1—ending poverty in all its forms, including child poverty.

  3. To achieve this, a comprehensive approach is necessary, one that addresses both income poverty and other facets of child deprivation in Nepal. This approach must effectively address disparities linked to geography, caste/ethnicity, disability status, and the nutritional and health status of households, among other factors.

  4. Our observations highlight actual outcomes, not just potential scenarios or what could be. One promising avenue in this context is the Under-5 Child Grant (U5CG). While it alone cannot resolve the broader issues of children’s agency and rights, it holds significant potential for alleviating income poverty, as evidenced by this study.
