The author used street-length, street-hierarchy-weighting and street-house-bearing to determine weights corresponding to residential density, which was then used to distribute population gathered at tract level to block group
level in Erie County, New York.
While using 25 percent as a cutoff between "higher" and "lower" proportion of a race/ethnicity in a block group
was somewhat arbitrary, our results were robust to different cutoffs and operationalizations (sensitivity analysis available upon request).
Prior work looking at neighborhood context and maltreatment has been done at block group
(Friesthler, Needell, & Gruenewald, 2005), tract (Coulton et al.
Per capita public assistance, census 2000 block group
Some products contain variables specific to our industry, such as estimates of deposits per household for each block group
, census tract and county.
The circle's radius was enlarged until it included the centroid of the next closest census block group
(based on the distances between centroids), and the number of cases was recalculated.
Zip code and block group
boundary files typically have to be purchased separately.
Next, we included measures of block group
population density and SES, distance to the nearest large supermarket, and distance to nearest recreation area in our models.

has had a number of recent articles published in SPINE, including "Safety and effectiveness of bone allografts in anterior cervical discectomy and fusion surgery" (Spine 2011;36(24):2045-2050), a collaboration between Drs.
In Mugglin and Carlin's (1998) medical study, disease counts are interpolated from the tract to block group
level using population counts, rural/ urban designation, and proximity to waste sites as covariates.
Our "baseline prevalence" is based on the racial/ethnic composition of the Census Block Group
to which the residence of the individual was geocoded.
