Income of informal labourers in rural areas: A survey dataset of northern mountainous regions in Vietnam

This article introduces a dataset that presents not only the income of informal labourers in Vietnam's northern mountainous regions but also rural labourers' characteristics and the factors affecting rural labourers' income. The data collection was conducted in five provinces: Tuyen Quang, Quang Ninh, Ha Giang, Yen Bai, and Bac Giang. Farmers and labourers without labour contracts in rural regions are the target groups. A total of 750 survey questionnaires were equally distributed across five provinces through the snowball sampling method; in all, data from 725 collected questionnaires were selected for analysis. The dataset was collected through a three-part survey. Nominal, ordinal, and scale were used in the survey questionnaire. Tables and bar charts present data outputs. Analysis of the data provided insight into the correlation between the rural labourers' income and factors that may prove beneficial for researchers and provincial policymakers interested in, and in charge of, social development in rural areas. The dataset was obtained as a reference source for intensive studies on socio-economic development in rural regions.
