The New Territories and Kowloon will continue to be the main areas of population growth over the next decade while Sha Tin will remain the most populous district, according to the government's latest population-distribution projection. In its report 'Projections of Population Distribution, 2007-2016', the Planning Department estimates that the number of people living in the New Territories will grow by 11 per cent to 3.96 million from 3.57 million last year. In Kowloon, the population will increase to 2.2 million in 2016, a rise of 10 per cent. Population growth on Hong Kong Island will be marginal - rising from 1.27 million last year to 1.28 million by 2017. The distribution projections are based on figures released by the Census and Statistics Department in July. The report showed that the share of the population of the New Territories in the total population will increase slightly, from 52 per cent last year to 53 per cent in 2016, while that of Hong Kong Island will fall from 19 per cent to 17 per cent. Kowloon's share in the total population is likely to remain stable at 30 per cent. Sha Tin is projected to remain the most populous district. Its population is estimated to reach 687,300 in 2016, up from 607,100 last year. Yuen Long will experience the greatest population growth, with 116,600 more people over the next 10 years, to reach 650,200 in 2016. While the projected median age of the population will reach 43.7 in 2016, Yuen Long will have the lowest median age, at 38.7, of any district. Wong Tai Sin is projected to have the highest median age, at 45.8 years. Yuen Long will also have the highest proportion of working-age population, increasing from 73.6 per cent in 2006 to 76.9 per cent in 2016. Hong Kong's fertility rate is among the lowest in the world. Figures show that in 1971 there were 3.46 children for every woman of child-bearing age; the ratio had fallen to 0.98 by last year. It is forecast to fall to 0.9 in the next 30 years. Tax benefits were given in February to encourage people to have more children.
