Month of birth


For all persons, BIRTHMO reports the person's month of birth.

Collection and Imputation of Age and Date of Birth Information 

Interviewers asked for the date of birth and age of each reporting unit member. AHRQ then calculated exact age from date of birth. In cases where the calculated age and the age provided did not match, AHRQ staff reviewed and resolved inconsistencies. When respondents did not provide the date of birth but did provide age, AHRQ assigned the month and year of birth randomly from among the possible valid options. For any remaining cases with missing age information, AHRQ imputed age using:

1. The mean age difference between MEPS participants with certain family relationships (where available), or
2. The mean age value for MEPS participants.
