Exposure assessment was based on residential block group
LUR estimates of outdoor annual average N[O.
Mean post-operative heart rate in the control group was significantly higher than that in the block group
The estimated number of commuters per block group
who reported bicycling or walking (ACS active commuters) was downloaded from the Census Bureau (5).
Three patients--two in the paracervical block group
and one in the control group--developed a cervical infection after surgery.
The geographic distribution of mammography capacity at the block group
level is highlighted in Figure 2.
Options considered for model development range from focused, high-resolution analysis of a relatively small number of samples (100 to 200) to a much broader analysis, considering the majority of block groups
(approximately 200,000), but with estimates generated for each block group
at lower resolution.
To evaluate possible associations between socioeconomic factors and plague risk, we used US Census Bureau decennial data to compare census block groups
(CBGs) in which human plague cases occurred and did not occur in New Mexico during 1976-2007.
Much of the current neighborhood-based research uses variables aggregated on administrative boundaries such as census tracts, block groups
, and zip codes to explore phenomena occurring within these geospatially bound social networks (Coulton, 2005; Coulton, Cook, & Irwin, 2004; Coulton, Korbin, Chan, & Su, 2001; Coulton, Korbin, & Su, 1999; Dietz, 2002; Grannis, 1998, 2005; Mayer & Jencks, 1989; Raudenbush & Sampson, 1999; Sampson, Morenoff, & Gannon-Rowley, 2002; Sampson & Raudenbush, 1999).
In the first stage of selection, 710 census block groups
were categorized by gonorrhea prevalence and number of households with at least one resident aged 15-24.
Beginning in 2010, five-year estimates will be released for populations with less than 20,000 people, down to the census tract and block group
Extended Block Group
of the Year was won by Thomas Gammell and Paul Maher (Cummins Turbo Technologies and Von Roll Isola).
Students' addresses were matched with Census block groups
and then classified according to the average SES characteristics of their block group
