Alaska BRFSS Health Profiles: Tribal Health Regions [HTML5]
This page is used to select InstantAtlas Maps to display BRFSS variables by tribal health region. The Alaska Native Epidemiology Center within the Alaska Native Tribal Health Consortium has divided Alaska into 12 tribal health regions. The boundaries of the tribal health regions do not always follow those of boroughs and census areas. A comprehensive definition of the regions can be found in Appendix A of the Alaska Native Tribal Health Report.
The user will also specify whether to depict actual prevalence estimates (termed "crude rates") or age-adjusted estimates which transform the prevalence as if Alaska had the same age structure as the United States 2000 Standard Population. Crude rates are useful for determining the percentage of the population at risk. Age-adjusted rates are useful for transforming survey responses into a standard age distribution when making comparisons between regions or across time periods.
InstantAtlas maps use space, color, magnitude, and direction to facilitate data visualization of health risk factors on maps and charts. Four templates or formats are used to display the BRFSS health profiles. The first three templates require use of an HTML5-compatible browser. The Single Map template combines a map, bar chart, and times-series chart for viewing a single variable across all regions. The Double Map template is a research tool that allows the selection of two variables (with their own maps) to be compared in a bi-variable graph across regions. The Double Map template is only available for use with age-adjusted data. A third, visual option is the Area Profiles - Spine Chart template which looks at multiple variables for a single region. A non-graphical option is available in the HTML Profiles template. Individuals desiring a text-based or accessible alternative, should choose the HTML Profile option.
Data files are available in comma-separated values (CSV) and Excel XSLX formats.
