In the Index of Economic Freedom created by Heritage Foundation, Hong Kong is ranked 1st and #Singapore is ranked 2nd in the world. Population density in Hong Kong is 6,777/km², but “the residential average population density calculates closer to a highly cramped 100,000/km².” Population density in Singapore is 7,804/km². And here is a chart which illustrates how these two countries cope with the #coronavirus, in comparison to other countries.
The chart operates on absolute numbers and starts from a 100th case, which for smaller countries means a higher percentage of population already infected.
