    Vital Signs: Migration - Bay Area

    data.bayareametro.gov | Last Updated 2019-10-25T20:40:04.000Z

    VITAL SIGNS INDICATOR Migration (EQ4) FULL MEASURE NAME Migration flows LAST UPDATED December 2018 DESCRIPTION Migration refers to the movement of people from one location to another, typically crossing a county or regional boundary. Migration captures both voluntary relocation – for example, moving to another region for a better job or lower home prices – and involuntary relocation as a result of displacement. The dataset includes metropolitan area, regional, and county tables. DATA SOURCE American Community Survey County-to-County Migration Flows 2012-2015 5-year rolling average http://www.census.gov/topics/population/migration/data/tables.All.html CONTACT INFORMATION vitalsigns.info@bayareametro.gov METHODOLOGY NOTES (across all datasets for this indicator) Data for migration comes from the American Community Survey; county-to-county flow datasets experience a longer lag time than other standard datasets available in FactFinder. 5-year rolling average data was used for migration for all geographies, as the Census Bureau does not release 1-year annual data. Data is not available at any geography below the county level; note that flows that are relatively small on the county level are often within the margin of error. The metropolitan area comparison was performed for the nine-county San Francisco Bay Area, in addition to the primary MSAs for the nine other major metropolitan areas, by aggregating county data based on current metropolitan area boundaries. Data prior to 2011 is not available on Vital Signs due to inconsistent Census formats and a lack of net migration statistics for prior years. Only counties with a non-negligible flow are shown in the data; all other pairs can be assumed to have zero migration. Given that the vast majority of migration out of the region was to other counties in California, California counties were bundled into the following regions for simplicity: Bay Area: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, Sonoma Central Coast: Monterey, San Benito, San Luis Obispo, Santa Barbara, Santa Cruz Central Valley: Fresno, Kern, Kings, Madera, Merced, Tulare Los Angeles + Inland Empire: Imperial, Los Angeles, Orange, Riverside, San Bernardino, Ventura Sacramento: El Dorado, Placer, Sacramento, Sutter, Yolo, Yuba San Diego: San Diego San Joaquin Valley: San Joaquin, Stanislaus Rural: all other counties (23) One key limitation of the American Community Survey migration data is that it is not able to track emigration (movement of current U.S. residents to other countries). This is despite the fact that it is able to quantify immigration (movement of foreign residents to the U.S.), generally by continent of origin. Thus the Vital Signs analysis focuses primarily on net domestic migration, while still specifically citing in-migration flows from countries abroad based on data availability.

    DOH Primary Care Service Areas

    highways.hidot.hawaii.gov | Last Updated 2023-03-24T00:48:23.000Z

    Department of Health Primary Care Service Areas: Received from State Dept. of Health, December, 2019. Boundaries are based on census tracts. Primary care service areas were selected to describe the delivery of primary health services in the State of Hawai‘i through participation of multiple stakeholders in the early 1990’s. The rural health associations of the Hawai‘i, Maui and Kaua‘i Counties delineated rational service areas under their respective jurisdictions. The Needs Assessment Committee of the Primary Care Roundtable participated in the delineation of rational service areas... referred to as primary care service areas. Clustering of neighborhoods into these primary care service areas was intended to provide information below the county or island level with demarcation between adjacent neighborhoods. Census tracts were used in defining these areas due to their availability in census and vital statistic data. The size of the population in these areas, based on the 2010 u.S. Census data, vary from 170 individuals in Ni‘ihau and 2,291 in Hāna to 115,164 in Ko‘olaupoko. Thus direct comparisons in estimates between primary care service areas are limited. Clusters of census tracts were defined using both 2010 and 2000 census tracts depending on the data source.

    Hawaii Brightfields Initiative Data as of September, 2019. HSEO has made it a priority to support informed renewable energy production in Hawaii. The Hawaii Brightfields Initiative database is intended to inform preliminary site due diligence and reduce soft costs associated with renewable energy development decisions. HSEO offers this resource to facilitate the reuse of previously developed or disturbed lands for renewable energy development in support of achieving its mandate of 100% renewable energy generation by 2045. For the purposes of the Hawaii Brightfields Initiative database, current site status regarding use, remediation, or actual or potential contamination has not been verified. Sites in this database may or may not have been assessed or remediated. Users should seek additional information and confirm actual site status and risks with the proper state and federal regulatory authorities, including HEER and/or the Hawaii Department of Health Solid and Hazardous Waste Branch. Information on specific individual sites may be found in HEER’s iHEER System(search by Tax Map Key number) and/or EPA’s RE-PoweringMapper(search by site key word, location, or name using the "Find" feature [Ctrl-F]).
