Singapore's birth rate has fallen below the replacement level of 2.1 since the 1980s before stabilizing during the 2000s and 2010s. (It reached 1.14 in 2018, making it the lowest since 2010 and one of the lowest in the world.) Government incentives such as the baby bonus have proven insufficient to raise the birth rate. Singapore's experience mirrors those of Japan and South Korea. In Taiwan, the average reported ideal family size among women aged 18 to 24 dropped from 2.1 in 1991 to 1.8 in 2003. In Hong Kong, that among women aged 18 to 27 fell from 1.8 in 1991 to 1.5 in 2011.
