This publication examines well-being across Kazakhstan's regions. It suggests how a deeper understanding of regional differences can help policymakers tailor interventions and promote more equitable development. The publication shares findings from a study that used data from a 2022 survey of well-being across Kazakhstan to create two indices. One index measures people's subjective well-being and the other combines perceptions data with objective socioeconomic data to build a broader picture of well-being. The authors analyze regions' index scores and suggest how policymakers can use an understanding of regional differences in well-being to contribute to more equitable, inclusive, and sustainable development in Kazakhstan.
