Steps to reproduce
The survey was conducted in Ho Chi Minh City and Dong Nai, the two largest provinces in the Southeast Vietnam to collect information for research on fertility. A multistage sampling method was applied with a designed sample size of 800 individuals of the main reproductive age, corresponding to the 95% confidence level, the 4.9% margin of error, and the estimated design effect of 2.0. In the first stage, seven communes, including one urban commune and one rural commune in Dong Nai and four urban communes and one rural commune in Ho Chi Minh City, were selected by using the PPS (probability proportional to size) method. The numbers of selected communes relatively reflect the levels of urbanization in each province. In the second stage, with an estimated non-response rate of 25%, about 533 households from two communes in Dong Nai and 533 households from five communes in Ho Chi Minh City were randomly selected for the target of 400 completed interviews in each province. An unmarried person or married woman aged from 18 to 45 years was randomly selected from each household to obtain her/his consent before interviewing. Information of family size desires and sociodemographic characteristics of married men were collected via interviewing their spouses. The CAPI method was applied with a structured questionnaire installed on smartphones via CSPro software version 7.3 to collect data. After a pre-test in early 2020, the main survey was carried out in May 2020, completing interviews with 808 individuals, including 382 cases from Dong Nai and 426 cases from Ho Chi Minh City, or 273 unmarried persons and 535 married women. Family size desires and socio-demographic characteristics of 535 married men were asked when interviewing their spouses. As such, the survey collected information on the family size desires of 1343 individuals. The dataset has been converted to SPSS format (version 26.0). For data analysis, the dataset need to be weighted (WEI variable) as individuals were not selected with equal probability.
