Information about the 2013 NCHS Urban–Rural classification scheme for
counties is available at https://www.cdc.gov/nchs/data_access/urban_rural.htm.
Large central metro are counties (or county equivalents) in metropolitan
statistical areas (MSA) of 1 million or more population that 1) contain the
entire population of the largest principal city of the MSA, or 2) are
completely contained in the largest principal city of the MSA, or 3) contain
at least 250,000 residents of any principal city of the MSA. Large fringe
metro are counties (or county equivalents) in MSAs of 1 million or more
population that do not qualify as large central. Medium and small metro are
counties (or county equivalents) in MSAs of 250,000 to 999,999 population or
in MSAs of less than 250,000 population. Nonmetropolitan are counties (or
county equivalents) in micropolitan statistical areas and non-core counties.

This variable is collected during rostering from a household respondent who
answered refuse or don’t know to the age of a household member who is
subsequently selected as the Sample Adult, and for whom the household
respondent indicated that the person is 18 and over. AGE65 may be
inconsistent with AGEP_A because AGEP_A is confirmed with the Sample Adult
respondent and uses date of birth to verify age. Analysts may use AGE65 when
AGEP_A is unknown for categorizing Sample Adults less than age 65 and 65 and
over.

In 2021, two similar life satisfaction questions were fielded in the LS1 and
LS2 sections of the Sample Adult module, one consisting of an 11-point answer
scale (LSATIS11_A) and the other consisting of a 4-point answer scale
(LSATIS4_A). The LS1 and LS2 sections were combined into the LS3 section in
this codebook. Starting in quarter 2, an experiment was embedded in the survey
to randomly change the order of which question the sample adult received
first. See variable LSROTATE_FLG for rotation order. This recode combines
responses to question LSATIS11_A administered in quarters 1-4. Note that
because the LS2 section was administered later in the survey, more not
ascertained (98) values are observed due to drop-offs when LSATIS11_A was
administered in the LS2 than LS1 section.
