Notes: We used sampling weights to calculate the summary statistics for each observation. We used the following formula to calculate the sampling weights: sampling weight = proportion of subpopulation in total population/proportion of subpopulation in sample. The subpopulation proportions in rural China’s total population are 37.7% for western China rural communities, 1.4% for resettlement migration communities, 42.0% for central China rural communities, and 18.8% for migrant communities. Next, in our sample, the subpopulation proportions are 82% for western rural communities, 5% for resettlement migration communities, 5% for central rural communities, and 8% for migrant communities. Therefore, the final sampling weights for each subpopulation are 0.46 for western China rural communities (equal to 37.7%/82%), 0.28 for resettlement migration villages (equal to 1.4%/5%), 8.4 for central China rural communities (equal to 42%/5%), and 2.35 for migrant communities (equal to 18.8%/8%). For the parenting practices, the first column shows the mean and standard deviation for the full sample; column 2 shows statistics for parenting practices in western China rural communities; column 3 shows statistics for parenting practices in resettlement communities; column 4 shows statistics for parenting practices in central China rural communities; column 5 shows statistics for parenting practices in migration communities. Column 6 shows the p-value of the difference between column 2 and column 3; column 7 shows the p-value of the difference between column 2 and column 4; column 8 shows the p-value of the difference between column 2 and column 5.
