Singaporeans are more satisfied with their lives than HongKongers

Check out this global map of average life satisfaction per country.

A global map of average life satisfaction levels by country based on the Gallup World Poll data looks much the same
as an income map of the world: the inhabitants of North America, Western Europe, Japan, Australasia, and Saudi
Arabia are both rich and well-satisfied with their lives, with average national life satisfaction scores in the range
of 7.5 to 8.5.

Singapore has average life satisfaction score of 6.4 while Hongkong has 5.4.

Here's more from Gallup:

The really unsatisfied places on the planet, with life satisfaction scores in the range of 3.1 to 4.5, are in sub-Saharan Africa, plus Haiti and Cambodia. The only countries in the bottom 20 according to life satisfaction that are relatively well-off in income terms are Georgia and Armenia, though it is possible that the income levels in both are greatly overstated.

At the other end, there are two relatively poor places in the top 20 in terms of life satisfaction: Costa Rica and Venezuela.

[The figure below] summarizes information about the relationship between life satisfaction and national income. The horizontal axis is per capita GDP in 2003 (the nearest year for which there is complete data in the Penn World Table) measured in purchasing power parity (PPP) dollars at 2000 prices. Each circle is a country, with diameter
proportional to population, and marks average life satisfaction and GDP for that country.

Important countries are labeled; most of the countries of sub-Saharan Africa are on the bottom left, India and China are the two large circles near the left, the Western European countries appear near the upper right, and the United States is the large country on the top right.

[The figure above] shows that life satisfaction is higher in countries with higher GDP per head. The slope is steepest among the poorest countries, where income gains are associated with the largest increases in life satisfaction, but it remains positive and substantial even among the rich countries; it is not true that there is some critical level of GDP per capita above which income has no further effect on life satisfaction.
