74 for women – levels seen in middle-income countries such as Brazil or Saudi<br />

Arabia (UNFPA, <strong>2007</strong>).<br />

China’s age dependency ratio 14 has been rising since the mid-1980s and this<br />

trend is set to accelerate. By 2030, the share of the population above the age of<br />

60 will more than double to 23.8%, equivalent to the level of Japan in 2000<br />

(Figure 7.7). Most of the elderly will live in urban areas. The number of<br />

workers for every dependant (elderly person or child) is projected to fall from<br />

2.1 at present to 2.0 by 2015 and to only 1.4 by 2030. The working-age<br />

population as a proportion of the total population is projected to peak as early<br />

as 2010 (Dunaway and Arora, <strong>2007</strong>). Age-related illnesses, such as cancer and<br />

cardiovascular disease, will become more prevalent, requiring an increase in<br />

health spending. Rapid ageing will also increase the burden on the public<br />

pension system.<br />
