We are interested in calculating how far away from you and from each other your children live. To do this we'd like to collect basic address information for each of your children -- just city/state and zipcode if you have it on hand. Please be assured that this information will be safeguarded and kept confidential. In what CITY and state does [name of child] live? Question text for 2004, 2006 and 2008: E146. CHILD NAME (In what city and state does [he/she] live?) Question text for 2010 and beyond: E146. In what city and state does CHILD NAME live? User Notes: (1) The E146 loop is repeated for each living child or child's surviving spouse/partner who is in contact and non-resident and who does not live within 10 miles of respondent. HRS asks about all new children and children who have moved since the family respondent's last interview. If the respondent has moved since the last interview, HRS asks about all children who live more than 10 miles from respondent. Further, HRS asks about all children living more than 10 miles from respondent for whom residence location information has never been obtained, and in 2010 and beyond, about all children living more than 10 miles from the respondent whose residence location was obtained more than four years ago. (2) During processing, the contents of CITY and STATE were reviewed for accuracy and corrected whenever possible. If the city name was ambiguous or missing, only the value of STATE was retained. (3) In situations where the child's ZIP Code was not provided, CITY and STATE (E146 and E147) were used to determine ZIP Code through look-ups using the Zip-Codes.com Standard ZIP Code database (http://www.zip-codes.com), the Google search engine (http://www.google.com), and other internet sources. If a city/state combination had multiple ZIP Codes, the first one on the list was assigned by the coder. (4) If ZIP Code was provided by the respondent, the value was checked against the Zip-Codes.com Standard ZIP Code database for consistency with CITY and STATE (E146 and E147). (5) If the respondent said that the child was living in a foreign country, the interviewer asked for the name of the country (E149). ................................................................................. ========================================================================================== STATE CHILD RESIDENCE USPS STATE (E148) Section: A Level: Child OPN Type: Character Width: 2 Decimals: 0 Ref: STATE E147.
