It is well suited to our data because features high products, includes money details about one another couples, which is consistent round the a lengthy time period. The new CPS includes details about the age of this new oldest child on the household, and that we use to proxy the new time of admission toward parenthood.
Most of all of our CPS analyses believe in a sample out-of partnered people where the partner try many years 45 or younger and you may their eldest child is age 0ten (N = 333,455 couples). The newest adjusted CPS test was affiliate of one’s noninstitutionalized society of heterosexual married couples in the united states where neither mate is within the armed forces, the new spouse try many years forty five otherwise younger, as well as the couple’s eldest youngster is actually age 0ten.
