Abstract
The average happiness in Kazakhstan is 6.6 on a scale of 0 to 10, which is in the mid-range of the countries' happiness ranking. Average happiness rose in Kazakhstan in the 2010s, but in 2009 and 2016, there was a decline in the country's happiness level. Possible reasons are discussed. Kazakhstanis experience low cognitive satisfaction with much higher levels of emotional well-being, which is also characteristic of developing post-Soviet countries. The inequality of happiness measured by the standard deviation in Kazakhstan is relatively high. According to this indicator, the country is in the mid-range in the ranking list. The correlates of happiness in Kazakhstan in several parameters differ from the pattern usually observed in developed countries and reflect those typical for developing countries of the post-Soviet space.
