About HART
Title
The title for the survey is as follows: Healthy, Aging and Retirement in Thailand (HART)
Background and Objectives
The Health, Aging, and Retirement in Thailand (HART) project is a sister study of the Health and Retirement Study (HRS) at the Institute for Social Research (ISR), University of Michigan (National Institute on Aging 2007) (See “Health and Retirement Study”). Since 2009, HART has been conducted through the collaborative efforts of researchers and faculty members from the Research Center, School of Applied Statistics, School of Development Economics, and School of Social Development, Intelligence and Information Center (NIDA IIC) under the Center for Aging Society Research (CASR), National Institute of Development Administration (NIDA). There were two pilot HART surveys in 2009 and 2011 with research grants from the National Research Commission of Thailand (NRCT) and the Commission of the Higher Education (CHE), respectively. The baseline (Wave 1) national HART project began in 2014 and Wave 2 began in 2016. Both projects were supported by research grants from NRCT. The data collected from the national surveys in 2015 (Wave 1), 2017 (Wave 2) and 2021 (Wave 3) are maintained in the data archive at the NIDA Intelligence and Information Center (NIDA IIC).
The primary objective of the HART project is to create a national longitudinal and household panel dataset on aging in Thailand that can be harmonized with the HRS (and its sister studies). In doing so, the HART data support research on the aging among Thai older adults from a multidisciplinary perspective and for advancing public policy to improve the quality of life and well-being of older adults in Thailand.
Survey Subjects
- One eligible member aged 45 or older is selected from each panel household as a primary respondent.
- Number of Samples: Healthy, Aging and Retirement in Thailand (HART) is a longitudinal panel study that surveys a representative sample of approximately 5,600 people in Thailand.
Survey Method
Computer Assisted Personal Interviewing (CAPI)
Survey Topics
HART is a biannual household panel survey designed to provide panel data on the multidisciplinary dimensions of aging in Thai older adults, including: (1) demographic characteristics, (2) family and transfers, (3) health and cognition, (4) employment and retirement, (5) income, (6) assets and debts, and (7) life expectations and life satisfaction.
The target population of the HART project is based on households in Thailand and uses the following multistage stratified random sampling design.
Stage 1: There are six strata of regions: (1) Bangkok and vicinity (Nonthaburi, Samut Prakan, and Pathum Thani), (2) East, (3) Central except Bangkok and vicinity, (4) North, (5) Northeast, and (6) South.
In the first stratum, all provinces (Changwats) are selected. Bangkok is the capital of Thailand and Nonthaburi, Samut Prakan, and Pathum Thani are vicinities and they are located in the middle of Thailand with many more older adults than in other provinces.
In the second stratum, in the east of Thailand, there are only seven provinces; each has relatively small numbers of older people and covers small geographic areas. Therefore, only one province is selected at random.
All provinces in stratum 3–6 are considered to be a “large-size” province, if it consisted of more than 300,000 households, and a “small-size” province otherwise. In each stratum, two provinces are selected at random, one from the set of large-size provinces and the other from the set of small-size provinces.
