China Health and Retirement Longitudinal Study

描述（由申请人提供）： 中国对人力资源调查的需求日益增长。中国的老年人口比世界上任何一个国家都多，是当今世界上老龄化速度最快的国家之一。中国人口老龄化的收入水平远低于工业国家，但比今天的发展中国家要快。到2030年，中国的老年人口比例预计将达到16%，超过新加坡、马来西亚、以色列和阿根廷等富裕国家。中国的老年人抚养比（25- 64岁的黄金年龄成年人与64岁以上老年人的比例）预计将从2000年的近13下降到2050年的2.1。中国的快速老龄化是由于寿命的增长（部分原因是中国收入的快速增长）以及与中国实施了25年多的独生子女政策相关的生育率迅速下降。然而，在经历了30年的快速增长后，2008年底开始，增长率急剧下降，这可能给中国的老年人带来他们无法预见的严重负面经济冲击。 2008年夏天，我们成功地开展了中国健康与退休纵向研究（CHARLS）的试点，该研究以美国的健康与退休研究（HRS）和其他HRS类型的调查为模式。我们收集了两个省的试点数据：浙江和甘肃。甘肃是中国最贫困的省份之一，农村人口众多。相比之下，浙江是中国工业化和向西部出口的主要中心之一。它的城市化程度远远超过甘肃省。我们获得了1，570个45岁及以上的家庭和2，685个人的样本（我们随机选择一个45岁以上的家庭进行采访，加上他们的配偶）。 现在我们建议在2011年和2013年举办前两次全国性的CHARLS活动。我们将在CHARLS中包括试点家庭，这将为用户提供一个直接的小组维度。我们预计样本量为10，210个家庭，其中一名成员超过45岁，包括试点家庭，以及17，635名个人，我们预计会采访他们。我们将跟踪已经搬迁的家庭和个人，以实现低流失率。 公共卫生相关性：中国健康与退休纵向研究（CHARLS）将丰富老龄化研究的国际格局。CHARLS将密切关注世界各地现有的健康与退休研究，以便为学者提供进行比较研究以及研究中国特殊情况的能力。查尔斯的前两次全国性浪潮定于2011年和2013年举行。

DESCRIPTION (provided by applicant): There is a growing need for a HRS-type survey in China. China has more elderly than any country in the world and is one of the fastest aging countries in the world today. China's population is aging at income levels far lower than was true for industrial countries and faster than today's developing countries. By 2030, China's elderly population share is expected to reach 16%, greater than much richer countries such as Singapore, Malaysia, Israel, and Argentina. China's elderly support ratio (the number of prime-aged adults 25- 64 to the number older than 64) is projected to fall from nearly 13 in 2000 to 2.1 by 2050. Rapid aging in China is caused by growing length of life, in part resulting from China's rapid income growth) combined with rapid reductions in fertility associated with the implementation of China's very strong One Child Policy, which has been in place for over 25 years. Yet, after 30 years of rapid growth, growth fell drastically beginning in late 2008, potentially giving the elderly in China a serious negative economic shock that they could not have foreseen. In the summer of 2008 we successfully fielded a pilot for the China Health and Retirement Longitudinal Study (CHARLS), which was patterned on the Health and Retirement Study (HRS) in the United States and other HRS-type surveys. We collected the pilot data in two provinces: Zhejiang and Gansu. Gansu is one of the poorest provinces in China and has a large rural population. Zhejiang, in contrast, is one of the leading centers of Chinese industrialization and export to the west. It is far more urban than Gansu province. We obtained a sample of 1,570 households with individuals 45 years old and older and 2,685 individuals (we randomly choose one person over 45 years per household to interview, plus their spouse). Now we are proposing to field the first two national waves of CHARLS in 2011 and 2013. We will include the pilot households in CHARLS, which will give users an immediate panel dimension. We expect a sample size of 10,210 households with a member over 45 years old, including the pilot households, and 17,635 individuals, whom we expect to interview. We will track households and individuals who have moved, to attain low attrition rates. PUBLIC HEALTH RELEVANCE: The China Health and Retirement Longitudinal Study (CHARLS) will enrich the international landscape of aging studies. CHARLS will follow closely the existing Health and Retirement Studies around the world in order to provide the capability for scholars to engage in comparative studies as well as studies of the special conditions in China. The first two national waves of CHARLS are scheduled for 2011 and 2013.
