Its perfect to your data whilst possess large products, includes income details about each other partners, in fact it is consistent round the a long time period. The brand new CPS comes with details about age the fresh earliest youngster throughout the home, which we use to proxy the brand new timing out-of entry to your parenthood.

Much of all of our CPS analyses rely on a sample out of married people the spot where the wife was years forty-five otherwise younger and the oldest youngster is decades 010 (Letter = 333,455 partners).
