FILE - In this Feb. 22, 2010 file photo, commuters make their way to work on a train in Singapore.

To accommodate the influx, its planners envisage expanding upward, outward and downward. The population target of 6.9 million people, an increase of 1.3 million from the present, is contentious in a country where rapid immigration has already strained services such as public transport and contributed to a widening wealth gap.
