Singapore has an ageing society. The median age has doubled from 19.5 years in 1970 to 38.4 years in 2012.
And the city-state is getting more crowded over the years. The total population per square kilometre has more than doubled from 3,538 in 1970 to 7,257.
But look at the progress in education. Almost a quarter of the population (24.5 per cent) aged 25 or more has a university degree, up from just 12.1 per cent in 2000 and only 4.7 per cent in 1990. In the last decade, the number of university degree holders has doubled in Singapore.
And finally a look at the population of citizens and permanent residents.
Singapore has 3.28 million citizens and over 533,000 permanent residents.
All the figures are from Population Trends 2012 released by the Department of Statistics, Singapore.
