Regional health-care inequity in children’s survival in Zhejiang Province, China

Background China is now under a period of social transition, and inequity is evident in the field of health care. We aimed to investigate regional health-care inequalities in children’s survival in Zhejiang Province, China. Methods In our study, monitoring data of Zhejiang Province from 2005 to 2014 was collected. The flow of data collection of community-district-city for urban areas or village-township-county rural areas was followed. The factors affecting equity was analyzed including regional economical level and household registry. We adopted standard measures of concentration curve and concentration index to evaluate degree of income-related inequity and the trend of mortality changes. Results From 2005 to 2014, overall mortality rate in children under five decreased, and regional disparity reduced markedly, and with a reduced disparity of mortality rate among children from urban and rural areas. In 2014, the mortality rate in children from urban and rural areas was similar. In contrast, the mortality rate in the children from migrant population was more than two folds of that in the children from native residency (7.82 ‰ vs. 3.89 ‰). The mortality rates of newborns (rs = −0.396, P
