Financial instability and high debt are major problems for young families in Kazakhstan. With inflation, rising living costs, and an unstable job market, a large portion of household income goes to paying off debts. This limits what families can spend, reduces their life satisfaction, and raises social risks. The main goal of this study is to examine how financial instability and debt affect the well-being of young families in Kazakhstan. This study uses quantitative methods, including a survey of 497 young families in Kazakhstan. We employed descriptive statistics and correlation analysis. These analyses helped us find connections between financial stability, debt levels, and family satisfaction. The results showed that a high level of debt negatively affects the well-being of young families. Over 66% of respondents have to cut back on spending because of credit payments, and 18.5% are in serious financial trouble. Correlation analysis showed a strong negative relationship between life satisfaction and attitudes toward credit (r = -0.681, p < 0.001), as well as the difficulty of managing payments (r = -0.523, p < 0.001). The study highlights the need for measures to improve financial literacy, create affordable credit programs, and provide state support for young families. This study is important for discussions in economic sociology and family policy. It can also help in creating effective strategies for Kazakhstan's socio-economic development.
