Annual Health Survey (AHS), India, 2007-2012

The Annual Health Survey (AHS), conducted by the Government of India between July 2010 and May 2013, investigates maternal and child health in nine states: Assam, Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Orissa, Rajasthan, Uttarakhand, and Uttar Pradesh. These states constitute about 70 percent of neonatal deaths in India and about one-in-five neonatal deaths globally. The AHS consists of a three-round panel that interviewed over 4 million households in each round, as well as a one-time Clinical, Anthropometric, and Bio-Chemical Survey (CAB). The data were originally released to the public in 2015 as a set of 45 .csv files. The .csv files are included in a restricted-use zipped package as part of the ICPSR release (see dataset 21). The survey focused on topics such as household composition, caste, fertility, family planning, pre- and post-natal care, breastfeeding, infant mortality, illness, disease, disability, and health care practices. Demographic information includes sex, age, education, occupation, marital status, household size, and religion. The CAB files contain biometric data including but not limited to height, weight, blood pressure, hemoglobin, pulse, and blood glucose. Potential data users should note that the public-use and restricted-use versions of the datasets are the same except for the masking of day component variables for certain dates in the public-use versions of the files (please see the Description of Variables section for full details). Therefore, only researchers with a limited set of research questions that require full birth, marriage, and death dates will need to apply for the restricted-use versions of the data files. Additionally, because the final data files are very large and potentially very time consuming to analyze on personal computers, researchers have the option to download ten-percent samples of each file (see datasets 3, 4, 7, 8, 11, 12, 15, 16, 19, and 20). These samples contain the same variables as the original files but only ten percent of the records. The samples were determined by taking a randomly selected ten percent of households in each district. P.I. codebooks were not produced for these samples. Please note that the ten-percent samples for each dataset were selected independently, so it is not advised to merge across datasets within the AHS using these samples, as the match rates will be very low.

《印度年度健康调查》（AHS），由印度政府在2010年7月至2013年5月期间进行，旨在探究九个邦（阿萨姆、比哈尔、查蒂斯加尔、达拉特南德、马哈拉施特拉、奥里萨、拉贾斯坦、喜马偕尔邦和乌塔拉普拉德什）的母婴健康状况。这些邦约占印度新生儿死亡总数的70%以及全球新生儿死亡总数的五分之一。AHS包括三轮调查小组，每轮对超过400万户家庭进行访谈，以及一次性的临床、人类学和生物化学调查（CAB）。数据最初于2015年以45个.csv文件的形式向公众发布。这些.csv文件包含在ICPSR发布的受限制使用的压缩包中（参见数据集21）。调查聚焦于家庭构成、种姓、生育率、家庭规划、孕前和产后护理、母乳喂养、婴儿死亡率、疾病、残疾以及医疗实践等主题。人口统计数据包括性别、年龄、教育、职业、婚姻状况、家庭规模和宗教。CAB文件包含包括但不限于身高、体重、血压、血红蛋白、脉搏和血糖的生物测量数据。潜在的数据使用者应注意，公共使用版和受限制使用版的数据集在除公共使用版本文件中某些日期的日分量变量被屏蔽外，内容相同（请参阅变量描述部分以获取完整详情）。因此，只有那些需要完整出生、婚姻和死亡日期的研究人员才需要申请受限制使用版的数据文件。此外，由于最终数据文件非常大，且在个人电脑上分析可能耗时较长，研究人员可以选择下载每个文件10%的样本（参见数据集3、4、7、8、11、12、15、16、19和20）。这些样本包含与原始文件相同的变量，但只有10%的记录。样本是通过在每个地区随机选取10%的家庭来确定的。对于这些样本，没有生成P.I.代码簿。请注意，每个数据集的10%样本是独立选取的，因此不建议使用这些样本在AHS内部合并数据集，因为匹配率将非常低。
