Codes and Frequencies
For sample persons under 5 years old, WAVEBYEV reports if the child has ever waved good-bye without help from another person.
Child motor and social development variables should be combined with AGE, BIRTHMO (Month of birth), and INTERVWMO (Month of NHIS interview) to provide complete information about the child's developmental progress. For more information on how the child's specific age is relevant to this variable, please see HEADTURNEV.
For related variables, please use the IPUMS NHIS search function and drop-down menus.
