The Quality of life index includes a number of indicators of well-being, which have been identified by the OECD as important for characterizing the development process of countries. The development process is considered by the OECD not only as a change in material or economic well-being, but also as an expansion of human potential.

There has been some progress in Kazakhstan on certain indicators included in the index.

Thus, in the aspect of «Housing conditions», there is a positive trend in indicators:

• reduction of the share of housing maintenance costs in total household expenses (from 12.1% in 2020 to 11.6% in 2022);
• reduction in the proportion of housing not equipped with central sewerage (from 11.6% in 2020 to 10.2% in 2022). However, the average number of rooms per person did not change and amounted to 0.8 rooms.

In such an important aspect as "Education", the average academic performance of 15-year-old students (according to the PISA educational rating, which includes mathematical, natural science and reading literacy) increased from 402 in 2018 to 411 points in 2022.

We note that in terms of the "Health" aspect, there is an increase in life expectancy from 71.37 years in 2020 to 74.44 years in 2022.

Quality of life is an interdisciplinary concept that characterizes the effectiveness of all aspects of human life.
