Comparability

In 1985 and 1990, this question was asked of all sample persons aged 18 and over with 1 smoke detector installed in the home. In 1994, the question was asked of half of sample persons. Changes in sampling frequency may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IPUMS NHIS weights.
