**2004 SMART BRFSS County Methodology**

**2004 Selected Metropolitan/Micropolitan Area Risk Trends from the
BRFSS **

**Creation of Metropolitan-level weights**

The Behavioral Risk Factor Surveillance System (BRFSS) Selected
Metropolitan/Micropolitan Area Risk Trends (SMART) is a documented and
verified subset of the 2004 BRFSS, which has been produced to provide
some local area estimates. These local areas are identified counties
within metropolitan or micropolitan statistical areas (MMSA) as defined
by the Office of Management and Budget. The data set was produced by
adding new analysis weights designed to correspond to the 2004
population estimates for each eligible county within a selected MMSA.
The additional weights were post-stratified to the county-level. The
process by which these new weights were obtained is detailed in Appendix
C, "Weight Class Collapsing Rules."

# [Selected Areas ]{.underline}

Typically, BRFSS data are used to produce state-level estimates.
However, for the SMART project, BRFSS data were used to produce small
area-level estimates for MMSAs as defined by the Bureau of the Census.
On June 6, 2003, the Office of Management and Budget (OMB) issued new
definitions for metropolitan statistical areas, micropolitan statistical
areas, and metropolitan divisions. OMB periodically updates the list of
MMSAs. The list of areas used for this analysis can be found at . For
more information about MMSAs, please visit . A respondent was associated
with a particular MMSA on the basis of their county code. Missing county
codes were imputed from a value included in the purchased telephone
sample that represents the county most likely associated with the
telephone number. There were 134 MMSAs that met the analysis criteria
for the 2004 data year. From within the 134 MMSAs, county-level
estimates have been produced from the BRFSS data for 199 counties that
have met the weighting criteria (Appendix C) for the 2004 data year.

collapsed across sex). ]{.underline}

[ 2 -- Female ]{.underline}

[\_CNTY -- FIPS county code of the county where the respondent lives.
This variable is equivalent to CTYCODE, except for respondents with a
CTYCODE of "777" or "999". The county code for these respondents was
imputed based on information provided by BSB. ]{.underline}

[\_CNTYNAM -- County name of the county where the respondent lives.

[\_CNTYWT -- the new county-level weight. This is the weight to use when
generating county-level estimates for questions that were asked of the
whole sample. ]{.underline}

**[Appendix C: Weight Class Collapsing Rules]{.underline}**

**[County]{.underline}[-level Weighting Methodology]{.underline}**

[Respondents were assigned to a county on the basis of their FIPS county
codes. Missing county codes were imputed from a value included in the
purchased telephone sample that represents the county most likely
associated with the telephone number before the respondent identifies a
county during data collection.]{.underline}

[All respondents in counties were then assigned to age, race, and sex
categories. If a respondent's age was missing, it was imputed by using
the variable \_IMPAGE available in the BRFSS public-use 2004 data file.
If a respondent's race was missing, it was imputed by using the majority
race for the county in which the respondent lives. The six age
categories were 18-24, 25-34, 35-44, 45-54, 55-64, and 65+. The two race
categories were white, non-Hispanic, and nonwhite or
Hispanic.]{.underline}

[Within each county, respondents were assigned to weighting classes on
the basis of the age, race, and sex categories described above. Some
states do not use race in post-stratification. For the county in states
that do not use race, only the age and sex groups were used to set up
weighting classes. For the county in states that do use race, all three
groups were used to set up weighting classes. Thus, the counties that
use race had 24 initial weighting classes and counties that do not use
race had 12 initial weighting classes. ]{.underline}

[Weighting classes with fewer than 19 sample members were collapsed in
accordance with the following rules:]{.underline}

1.  [For those counties that used race in post-stratification, the race
    categories within a sex category collapse if at least 80% of the age
    categories in that race /sex cross-classification (i.e. 5 of 6 the
    age categories) have fewer than 19 members. In counties that used
    race to create the initial weighting classes, the number of
    weighting classes was thus reduced from 24 to 12 if race was
    collapsed for both sexes and from 24 to 18 if race was collapsed for
    only one sex.]{.underline}

2.  [Collapse the two youngest age categories in any age/sex or
    age/sex/race weighing class if either contains fewer than 19
    members. Do the same for the two middle and the two oldest age
    categories in each remaining weighting class. ]{.underline}

3.  [If either of the age/sex or age/sex/race categories have fewer than
    19 members, then the age categories were collapsed until there were
    19 members in some combination of the age categories listed in the
    variable AGE_C_F.]{.underline}

4.  [Do not collapse weighting classes across sex.]{.underline}

5.  [Do not include a county in the reweighting that still has weighting
    classes with fewer than 19 sample members after all collapsing rules
    have been applied. These counties will be excluded from the 2004
    SMART BRFSS. ]{.underline}

[There were 134 MMSA that had at least 500 respondents in the 2004 BRFSS
and at least 19 sample members in all final weighting classes. There are
199 counties within the 134 MMSA that had at least 19 sample members in
all final weighting classes. See Appendix B in the Data Documentation
for a list of these counties. Only the respondents in these counties
were given a county-level weight. To calculate the new county-level
weight, we applied a post-stratification adjustment factor to the design
weight (\_WT2) and created the adjustment factor by taking the ratio of
the total population over the sum of the design weights for each
weighting class within each county. The new county-level weight
(\_CNTYWT) should be used to generate estimates in these 199
counties.]{.underline}
