Increasing within-country migration from rural to urban areas is setting new challenges for survey organization. For example, the educational level of population in urban and rural areas differ, resulting in differences in health behaviours and health outcomes between areas. Data from the national cross-sectional surveys of the FINRISK Study conducted in Finland in 1997-2012 among the adult population were used. Women living in the capital region were more likely to be survey non-participants than women living in rural areas. The differences between rural and urban areas have diminished over time among men, but not among women. Even though participation rates between different levels of urbanizations are becoming similar, observed differences in population profiles - that is, educational level - between areas may bias survey results unless results are adequately adjusted.
农村向城市的国内人口迁移增加，给调查组织带来了新的挑战。例如，城乡人口的教育水平不同，导致地区间的健康行为和健康结果存在差异。本研究使用了芬兰在 1997-2012 年进行的全国横断面调查 FINRISK 研究中成年人的数据。居住在首都地区的女性比居住在农村地区的女性更有可能不参与调查。男性城乡之间的差异随着时间的推移而缩小，但女性则不然。尽管不同城市化水平之间的参与率变得越来越相似，但如果不对结果进行适当调整，地区之间人口状况（即教育水平）的差异可能会使调查结果产生偏差。
