This thesis investigates the relationship between municipal finances, socioeconomic factors, and child poverty across 61 Norwegian municipalities classified within KOSTRA groups 9 to 12. Using municipal account data from 2015 to 2022, the analysis focuses on five key budgetary components; expenditures, revenues, general grants, tax income, and net loan debt, and their association with the share of children living in low-income households. In addition, it examines how local unemployment rates and education levels correlate with child poverty. The thesis applies both descriptive analysis and fixed effects regression model to assess within-municipality variation over time. The results show that increased municipal expenditure is significantly associated with lower child poverty, supporting the hypothesis that local spending can play a role in poverty reduction. Other budget components, such as general grants and tax income, present mixed or counterintuitive patterns. General grants are positively associated with child poverty, likely reflecting structural redistribution to disadvantaged areas, while tax income shows a negative but statistically insignificant relationship. Borrowing appears to have limited explanatory power. Socioeconomic variables, including unemployment and education levels, follow expected trends in the descriptive data but do not show significant effects in the regression model. These results suggest that child poverty is driven more by long-term structural factors than by short-term changes at the municipal level. The thesis reinforces the limitations of relying solely on local fiscal tools to reduce child poverty and highlights the importance of coordinated national policy, structural redistribution, and targeted social investments. The eight-year timeframe may not fully capture the long-term dynamics of child poverty, pointing to the need for extended time series in future research.
