TORTOISE AND HARE
But both countries must rise to meet monumental challenges. China is now confronting what has become known as the "one-two-four problem"--that is, one child caring for two parents as well as four grandparents. This harsh legacy of the country's one-child policy has profound implications for health and well-being in China as the population ages. It also promises to reweave China's social fabric and may place huge strains on the economy.
Particularly in rural areas, millions of elderly could saddle the country with what Nicholas Eberstadt, a political economist on the Visiting Committee at HSPH, calls a "slow-motion humanitarian tragedy, already under way." Eberstadt predicts a dire existence for this group, citing their lack of accumulated capital, their inadequate education, and the absence of a state-funded pension system to provide for them. "A third of Chinese women retiring in two decades will have no sons," he says, adding that most--despite being potentially ill and frail--will have to support themselves through farm labor.
India, despite recent progress, must grapple with staggering health issues. HIV infections alone are expected to quadruple in the next four years to 20 million cases, up from 5.7 million now, according to UNAIDS. Yet in 2005, the World Health Organization reports, India had less than one hospital bed, and one doctor, for every 1,000 residents. In the countryside, one doctor may be responsible for as many as 200,000 people.
A further problem is the emergence of chronic diseases, such as cancer, lung disease, heart disease, and diabetes, linked to rising rates of smoking and obesity and, ironically, longer lifespans and higher incomes. Both China and India face the problem of providing health care for people with these chronic diseases while still tackling a widespread infectious disease burden. In both countries, the public health system is failing to meet demand.
LESSONS TO BE LEARNED
Looking forward, China and India will have to address the fundamental demographic shifts occurring within each country, as well as swiftly widening socioeconomic disparities that could prove politically destabilizing. Bloom notes that while China has pursued a policy of mass education, India's educational focus has centered more on the middle class and elite. China is increasingly divided between affluence in the cities and poverty in the countryside; similarly, India's northern states are desperately poor, while the South claims the lion's share of educated, upwardly mobile people. Bloom and Canning have begun to investigate these regional differences with their colleagues.
"India and China are so big that the populations of some of their states and provinces, respectively, are larger than the population of many countries," Canning says. "And there are big differences between regions that potentially make treating each country as a single unit misleading."
Lessons learned from China and India have great value elsewhere, the HSPH researchers agree. China has made remarkable strides in alleviating poverty, Bloom says, adding that "aid agencies, donor countries, and developing countries will benefit from a greater understanding of China's experience." And India has nurtured an information technology sector with an increasingly global reach. The prospects for India look good for the next 30 years as its demographic dividend matures and it follows in China's footsteps. China's prospects are less clear. A rapidly aging population may lead to a reduced rate of economic growth and put new pressures on health and social security systems that are as yet unprepared for the task. Although India, too, will inevitably face similar pressures, its day of reckoning with population aging is less imminent.
