*The variance here will signify the distribution of random effects and the variability accounted by adding indicator separately.

†State mean years of the highest education completed by father were 5.5 years.

‡ANC denotes antenatal checkup; State proportion for women who had received ANC care was 44%.

¶The state proportion for urban population was11.3%.

**SE denotes standard error.

CI denotes confidence interval.
