Codes and Frequencies
For sample persons under 5 years old, HEADRAISEV reports, when lying on stomach, if the child has ever raised his or her head and chest from the surface while resting weight on lower arms or hands.
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.
