The Whittier Narrows Earthquake Study examined Los Angeles County residents' experiences during, and responses to, the Whittier Narrows Earthquake which occurred on October 1, 1987, and measured 5.9. Telephone interviews were conducted with 690 residents of Los Angeles county between October 1988 and May 1989. Information was collected on topics such as evacuation, personal property damage, disaster/emergency planning and preparedness, and respondents' psychological and emotional distress as a result of the earthquake experience. Demographic variables include gender, age, income, ethnicity, religious preference, home ownership status, education level, marital status, employment status and industry, and area of Los Angeles county where the respondent resided.

The sample was comprised of two strata: a high intensity stratum which was oversampled, and the rest of the county. The high impact areas were identified as incorporated communities where Modified Mercalli Intensities (MMI) were 7 or greater on a scale of 0 to 12. MMI provides an estimate of the amount of shaking that a geographic area experienced on October 1, 1987, the day of the earthquake. The high impact strata contained the cities of Monterey Park, Rosemead, El Monte and South El Monte where the MMI was 7 and Whittier with an MMI of 8. Households were selected using random digit dialing methods. Kish tables were used to select the designated respondent from those 18 and over who resided in the household on October 1, 1987, the date of the Whittier Narrows Earthquake. Telephone numbers were not pre-screened. Within the high impact area, interviews were conducted with 191 of the 254 eligible households identified. In the remainder of the county, interviews were conducted with 499 of the 1,190 numbers assumed to be eligible for the survey.

2013-05-29 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
  • Checked for undocumented or out-of-range codes.

The data are not weighted and no weight variables are present in the data. However, the high intensity area of Los Angeles County (Monterey Park, Rosemead, El Monte, South El Monte, Whittier) was intentionally oversampled to obtain approximately 200 interviews in that area. When population parameters are desired, respondents in the high intensity stratum must be weighted at .44, and respondents in the rest of the sample are weighted at 1.0.
