Based on the representative population survey data of early childhood development in China's underdeveloped regions, developed regions, and a megacity (Shanghai) between 2017 and 2018, the study uses the early Human Capability Index (eHCI) The tool assessed the early childhood development level of 63,559 children aged 36-59 months
.

The study defined the child’s overall development score exceeding the 20th percentile of the sample population as normal development, and estimated early childhood from five dimensions: gender, family income, mother’s education level, household registration type, and mobility or stay-behind status.
Develop the balance of normal proportions (absolute value)

The study found that the proportion of normal children in underdeveloped areas was 71%, in developed areas it was 82%, and in Shanghai it was 86%
.

Before adjusting for confounding factors, the imbalances in early childhood development in all five groups were statistically significant

As the country with the second largest child population in the world, there are still few relevant studies on the aspects of early childhood development (ECD) of disadvantaged children in China
