摘要：High surrounding road density could increase trafc-related air pollution, noise and the risk of trafc injuries, which are major public health concerns for children . We collected geographical data for all childcare centers (16,146) in Australia and provided the data on the road density surrounding them . The road density was represented by the child care center’s nearest distance to main road and motorway, and the length of main road/motor way within 100~1000-meter bufer zone surrounding the child care center. We also got the data of PM2.5 concentration from 2013 to 2018 and standard Normalized Diference Vegetation Index (NDVI) data from 2013 to 2019 according to the longitude and latitude of the child care centers . This data might help researchers to evaluate the health impacts of road density on child health, and help policy makers to make transportation, educational and environmental planning decisions to protect children from exposure to trafc-related hazards in Australia .
