Abstract
The first wave of the MIDUS study collected survey data from a total of 7,108 participants. The baseline sample was comprised of individuals from four subsamples:
- a national RDD (random digit dialing) sample (n=3,487);
- oversamples from five metropolitan areas in the U.S. (n=757)
- siblings of individuals from the RDD sample (n=950); and (4) a national RDD sample of twin pairs (n=1,914).
All eligible participants were non-institutionalized, English-speaking adults in the coterminous United States, aged 25 to 74. Data from the above samples were collected primarily in 1995/96.
