The Gateway to Global Aging Data (Gateway; g2aging.org) is a data and information platform developed to facilitate cross-country analyses on aging, especially those using the international family of Health and Retirement studies. We provide a brief introduction to the Gateway to Global Aging Data, discussing its potential for cross-national comparisons of family, social environment, and healthy aging.
We summarize the survey metadata, study characteristics, and harmonized data available from the Gateway, describing the population represented in each study. We portray cohort characteristics and key measures of health and social environment from 37 countries in North America, Europe, and Asia using harmonized data.
Significant cross-country heterogeneity was observed in many measures of family, social environment, and healthy aging indicators. For example, there was a threefold difference in coresidence with children, ranging from 14% in Sweden to over 46% in Spain and Korea in 2014. From 2002 to 2014, the difference between informal care receipt in individuals of low and high wealth decreased by 6% in the United States and remained unchanged in England. The percentage of individuals aged 50-59 living alone in 2012 varied 15-fold, from a low of 2% in China to a high of 30% in Mexico.
By partnering with nationally representative studies around the globe, the Gateway to Global Aging Data facilitates comparative research on aging through the provision of easy-to-use harmonized data files and other valuable tools.
全球老龄化数据网关（Gateway；g2aging.org）是一个数据和信息平台，旨在促进老龄化的跨国分析，特别是那些使用国际家庭健康与退休研究系列的分析。我们简要介绍了全球老龄化数据网关，讨论了其在家庭、社会环境和健康老龄化的跨国比较方面的潜力。
我们总结了网关中可用的调查元数据、研究特征和协调数据，描述了每个研究中的代表性人群。我们使用协调数据描绘了来自北美、欧洲和亚洲的 37 个国家的队列特征和健康与社会环境的关键指标。
在家庭、社会环境和健康老龄化指标的许多方面都观察到了显著的跨国异质性。例如，与子女共同居住的比例存在很大差异，从 2014 年瑞典的 14%到西班牙和韩国的 46%以上。2002 年至 2014 年，美国低财富和高财富个体接受非正式护理的差异减少了 6%，而英国则保持不变。2012 年，50-59 岁独居个体的比例差异高达 15 倍，从中国的 2%到墨西哥的 30%。
通过与全球具有代表性的国家研究合作，全球老龄化数据网关通过提供易于使用的协调数据文件和其他有价值的工具，促进了老龄化的比较研究。
