title: New York City Community Health Survey, 2003
title: Version 1

description: The 2003 New York City Community Health Survey (CHS) obtained telephone interviews with a representative sample of 9,802 adults age 18 years and older living in the 5 boroughs of New York City. This study is comprised of two parts: Part 1, Public Use Survey Data, and Part 2, Public Use Smoking Supplement Data. Part 1 contains questions regarding general health status, mental health, health care access, cardiovascular health, diabetes, asthma, immunizations, nutrition, physical activity, HIV, and sexual behavior. Part 2 focuses on smoking habits of respondents, second hand smoke exposure, and alcohol consumption. Interviews were completed in English, Spanish, Russian, Chinese (Mandarin and Cantonese), as well as multiple other languages, according to the preference of the respondent. The interviews were conducted by Baruch Survey Research Unit between April 10 and August 22, 2003. The sample was geo-stratified to collect interviews from 42 United Hospital Fund (UHF) areas in New York City. Weights were constructed at the UHF-level to allow the sample to provide neighborhood-level estimations of both individual adults and of households in New York City. The margin of sampling error for the complete set of weighted data is +/-1.44 percent for citywide household estimations, and +/-1.56 percent for citywide individual-level estimations. A core group of demographic variables are included to facilitate weighting and comparisons among different groups of New Yorkers. These demographic variables include gender, age, marital status, employment status, race, income, and educational attainment.
description: The telephone sample was provided by MSG-Genesys, Inc. according to Baruch's specifications. The sample was drawn using standard list-assisted random digit dialing
methodology.
The questionnaire was developed by the New York City Department of Health and Mental Hygiene (DoHMH), with consultation from Baruch. The survey instrument was composed of questions from the Behavioral Risk Factor Surveillance System (BRFSS), the National Health Interview Survey (NHIS) and other established national surveys, plus a small number of questions to address the unique needs of the DoHMH.
Trustforte Translation Services translated the final questionnaire into Spanish. Both English and Spanish were then programmed into a CATI instrument. The DoHMH translated the instrument into Russian and Chinese translations. Interviews in other languages, were conducted using live translation services provided by Language Line Services.
Calls were staggered over times of the day and days of the week to maximize the chance of making contact with potential respondents.The CATI program randomly selected an adult to be interviewed, distinguishing by sex and age (for
example, asking for the "second-oldest female"). This random selection was slightly biased toward men: 60-40.
description: Individual Weighting Formula

The initial weighting scheme was based on the following:
Number of adults in HH/Residential lines in HH (limit of 2) x Telephone noncoverage factor; 
The UHF Population factor = Adult population (UHF or ZIP code)/Sum of probabilities of adult selection; 
The Final weight was based Raking factors x Probability of adult selection x Population factors; 
Household Weighting Formula

The Individual weighting scheme was based on the following:
Number of adults in HH (capped at 3); 
The UHF Household factor: Number of households with adults 18+ Adult population/Sum of probabilities of household selection; 
The Final weight was based on Raking factors x Initial weighting x Household factors;
description: 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:
			   		Performed consistency checks.; Created variable labels and/or value labels.; Created online analysis version with question text.; Performed recodes and/or calculated derived variables.; Checked for undocumented or out-of-range codes..

					Based on the final dispositions of numbers dialed for
the survey, Response Rate 3 is 44 percent and Cooperation Rate 1 is 58 percent.

				   		Smallest Geographic Unit: ZIP code aggregations called UHFs
description: The sample is designed to generalize to the New York City adult population age 18 years and older, and to allow separate analyses of responses for 42 UHFs across the city. The design uses random-digit dialing (RDD) methods.
The telephone sample was provided by MSG-Genesys, Inc. according to Baruch's specifications. The sample was drawn using standard list-assisted random-digit dialing
methodology. Every active block of telephone numbers (area code + exchange + two-digit block number) that contained one or more residential directory listings was equally likely to be selected. This method guarantees coverage of every assigned phone number regardless of whether that number is directory listed, unlisted, or too new to be listed. After selection, numbers were compared against business directories and matching numbers were purged.
Additionally, randomly generated numbers that were not listed households were then dialed by MSG using their ID-Plus system, to remove businesses and nonworking numbers.
Strata sizes were established for each of the 42 UHF district. Once a UHF reached the target, all unresolved telephone numbers with exchanges that were at least 90 percent likely to be in a completed UHF were automatically statused as "over quota", as these numbers were extremely
likely to fall in strata that were completed. (While RDD sample includes a predicted ZIP code based on the relationship between telephone exchange and ZIP codes for listed numbers, the predicted ZIP codes match reported ZIP codes less than half the time. Therefore, exchange and ZIP code data from actual completes were used to guide the suppression of numbers.)
