Migration rate is a piece of critical information in social studies. It seems that other methods, rather than census which can perform better in costs and data updating, are more preferable. The purpose of this study was to investigate the estimation methods for internal migration based on formal information existing in databases which government can access and control; as well to propose solutions for accurately estimating integrated internal migration with the county resolution. The data obtained from migrants suggested that accuracy rate for Ministry of Education's information portal was 93% regarding to migrant children records. The Health Ministry information database had a coverage rate of 38.6% for filing and 28.2% for frequent visits over the migrant population. In total, using Health Ministry, Education Ministry, Social security insurance organizations, and medical treatment services organization databases, in combination with government personnel information portal, it was possible to estimate the city to city movements with up to 80% reliability.
