InfoAlameda's dynamic mapping platform provides powerful data covering a large range of demographic and other information relating to our communities. Many types of analysis and data work cannot be made available in the mapping system or require much higher standards for output than any automated mapping tools can provide in addition to much more extensive research and analytical background. Our customized demographic stydies and data products are made available online in this section, you can drill down to an area of interest below or just search our archive below. Newer work will always appear at the top of this page.

We noticed a lot of articles lately about the aging bay area population and decided to take a look at just Oakland.
We threw together the last three decennial censuses: 1990, 2000, and 2010 and plotted the 5-year age categories. For comparison, we added the California 2010 Age Profile. The percentages represent the proportion of the total population represented by the age categories for that particular census count.
One interpretation of the chart is that Oakland continues to lose young people during their school age years. We continue to house college students and just start workers, but not the same amount as before--this could be the closing of the military bases. We also seem to have an age-in-place population (the baby boomers) that are chunking ahead in 10 year intervals; they are now in their mid-50s to early 60’s (probably a good time to get into the health profession).
Census 2010 Demographic Profiles down to census designated places are available for download. Data categories include age, gender, race, and housing.
Matt Beyers at the Alameda County Public Health Department was good enough to send us a well-organized spreadsheet for Alameda County and its 20 CDP's. So, download and thank Matt for the time he has saved us.
2010 Census Population Changes in Alameda County Cities
Written by SpikeWe're being bombarded with questions about the changes in population in Bay Area cities today. To help answer some of those questions we're releasing some data tables of the city level population changes -- in particular, the changes in population amongst different ethnicities. These tables are available to download in Excel format or as a PDF.
The following table lays out the changes in population counts - the number of people gained or lost in each city by ethnicity. The county gained 57,227 persons in the 10 years between 2000 and 2010, with a loss of 23,982 Black/African-American persons and an increase of 93,200 Asians. The city of Oakland lost 32,989 Blacks and gained 9,912 Whites, while Fremont lost 26,648 Whites and gained 33,167 Asians. Hayward saw an increase of 10,880 Hispanics.
Alameda County African American Population Changes in 2010
Written by SpikeWith the release on March 8th of the new Redistricting data, the Census 2010 data is finally here! To follow up from our recent look at the African-American population across the Bay Area we are providing some preliminary maps that highlight the changes between the 2000 and 2010 Census.
The first images can be opened by clicking on them directly and a popup should appear, you can then scroll back and forth between the 2000 and 2010 maps for easy visual comparison.

New Census Tracts for 2010
This map shows changes to the 2010 census tracts from the 2000 census tracts. The primary changes that are indicated here are where one census tract has been split into either two, three or four tracts (the majority into two tracts). Tracts are split when there is enough of a population increase within the tract to warrant dividing the tract into a smaller geographic unit, so this map on a simple level shows where there has been significant population increase since the last census was taken in 2000. This map indicates population growth in Alameda County, especially in Emeryville and Dublin.

Tracts are a basic unit of measurement from which we can look at and analyze all sorts of information, not just population. There are political, demographic, and economic data that can all be summarized by tracts and then used to better understand the state of these affairs in the past, present and trends for the future. With this information (and specifically by displaying this information on maps) we hopefully can make better decisions for our local community.
Census tract boundaries normally follow visible features, but may follow governmental unit boundaries and other non-visible features in some instances; they always nest within counties. Designed to be relatively homogeneous units with respect to population characteristics, economic status, and living conditions at the time of establishment, census tracts average about 4,000 inhabitants.
