Instructions to Create Family Estimates. The variable FAMSIZ13 indicates the number of persons associated with a single family unit after students are linked to their associated parent RUs for analytical purposes. Family-level analyses should use the FAMSIZ13 variable. In a few cases, students were deleted from the file because attempts to contact them were unsuccessful, and no data were collected for them. However, these persons are accounted for in the FAMSIZ13 variable. The family size (FAMSIZ13) and the reporting unit (RU) size (RUSIZE13) counts may not be consistent with the count of records on the file. There are some reporting units where the RU size variable (RUSIZE13) is not equal to the number of people in that RU actually included on the file. This occurs because people who did not respond for their entire period of eligibility were not included on the file. In addition, for a number of these reporting units, the reference person is not included on the file for this same reason. The variable RURSLT13 indicates the RU response status for Round 3 for the Panel 17 sample and Round 1 for the Panel 18 sample. The values include the following: 60 Complete with RU member 61 Complete with proxy--all RU members deceased on or after 1/1/2013 62 Complete with proxy--all RU members institutionalized or deceased on or after 1/1/2013 63 Complete with proxy, other There are several other variables that characterize the reporting unit. The variable RUCLAS13 indicates the RU classification. RUs are classified for fielding purposes as 1 “Standard”, 2 “New RU”, or 3 “Student RU”. Standard RUs are the original RUs from the NHIS. A new RU is one which has been created when members of the household leave the standard RU and are followed according to the rules of the survey. A student RU is one in which an unmarried college student under 24 years of age is considered a usual member of the household but was living away from home while going to school and was treated as a Reporting Unit (RU) separate from that of their parents for the purpose of data collection. The reference period is the period of time for which data were collected in each round for each person. The reference period dates were determined during the interview for each person by the CAPI program. The round-specific beginning reference period dates are included for each person. These variables include BEGRFD13, BEGRFM13, and BEGRFY13. The reference period for Panel 18 Round 1 for most persons identified at NHIS began on January 1, 2013 and ended on the date of the Round 1 interview. Persons who joined the RU after January 1, 2013 have their beginning reference date for the round as the day they joined the RU. For Panel 17 Round 3, the reference period for most persons began on the date of the previous round’s interview and ended on the date of the current round’s interview. Persons who joined after the previous round’s interview had their beginning reference date for the round set as the day they joined the RU. The dates of the interview and the ending reference period dates are included for each person. These variables include ENDRFD13, ENDRFM13, ENDRFY13, RUENDD13, RUENDM13, and RUENDY13. In general, the date of the interview is the reference period end date for most persons. Note that the end date of the reference period is prior to the date of the interview if the person was deceased during the round, left the country, was institutionalized prior to that round’s interview, or joined the military during the round and was not living with someone else who was eligible. Because of this, it is possible for a person whose reference period for Round 3 ended in 2012 to be included in this delivery. While these few persons do not have a positive person-level weight for 2013, they are included in this file because they do have a positive family-level weight for 2013. If a person left the RU and that person was key and in-scope, the person was followed in the new RU to which he or she moved and his or her reference period dates pertain to the new RU.
