One of the biggest trends, as revealed by the Census 2010 data, is the increasing diversity of the U.S. population.
The 2010 Census allowed the reporting of six race categories and any combination of the six, as well as Hispanic or Latino ethnicity. As these many groups change over time, it is important to be able to track the change as a whole. To accomplish this, Esri created a proprietary Diversity Index. The Diversity Index is measured on a scale of 0 to 100 and defined as the likelihood that two persons, chosen at random from the same area, belong to different race or ethnic groups. If an area’s entire population belongs to one race group and one ethnic group, then an area has zero diversity. An area’s diversity index increases to 100 when the population is evenly divided into two or more race/ethnic groups. It is important to note Continue reading

Have you seen people on television spending hours a day clipping coupons in order to come home with thousands of dollars of groceries for mere cents? Do you subscribe to online sites that offer daily deals for goods and services in your area at 50% off or more? Do you read any blogs on how to save money or visit websites to find online coupon codes?

Valentine’s Day…it’s a holiday that some Americans love and some love to hate.
In the spirit of the holiday, we thought it would be interesting to take a look at the newly released 2005-2009 American Community Survey (ACS) data to find out where in America people are more likely to be married or single.
First, let’s take a look at a color-coded map of the percentage of the population age 15 years or older that is single – which includes those that are not married, are widowed, or are divorced. The county with the highest percentage of singles, according to the 2005-2009 ACS estimate is Kalawao County, Hawaii where 75.6% of the population age 15 years and older are classified as single. In Rosebud County, Montana, the percentage is much lower with 40.4% of the population classified as single.
Here is a color-coded map of the 2005-2009 ACS data on the percentage of the population age 15 years or older that is married. Ironically, Loving County, Texas has one of the cutest county names in the U.S. and the highest percentage of population that is married, at a whopping 93.6%.
We can also use the 2005-2009 ACS data to compute a male to female ratio. Baker County, Georgia is a promising place for single men. There are 74.3 males for every 100 females there. Conversely, in Lassen County, California there are 187.8 males for every 100 females. In Love County, Oklahoma there are 95.1 males for every 100 females.
ACS Data, shown in the maps above, is released annually by the Census Bureau. It is based on a rolling survey and has replaced the long form of Census 2000. Now data about income, education, employment, language, migration, citizenship, marital status, and housing characteristics, such as value and rent, will be obtained from the ACS instead of the census sample. To use data from the ACS, it will be necessary to incorporate estimates of sampling error or margin of error (MOE) which is included with all ACS estimates.
For more information on ACS Data, please visit our Resource Center on Census 2010 and ACS Data where you can ask questions and provide feedback directly to our Data Development team. We also encourage you to read three ArcUser Online articles written by Lynn Wombold, Esri Chief Demographer, on the topic ACS. These articles are entitled:
- Changes and Challenges: Understanding American Community Survey Data
- Sample Size Matters: Caveats for users of ACS tabulations
- Examining Error: Consider the effect of sample size and error source when using Census data
Note: These maps do not include the Margin of Error (MOE) for each estimate.
Happy Valentine’s Day!

The American Community Survey (ACS) replaces the traditional sample data collected during the decennial census. This change from a census sample to the ACS creates both challenges and opportunities for all data users. An understanding of the change in variable definitions, methods of collecting and reporting the data, sample weights, and standard errors (Margin of Error or MOE) will be necessary in order to use the ACS data.
Do you have any questions about ACS or Census 2010 data? Do you need more information about ACS data and the exact changes that will occur? Do you want to better understand the Margin of Error and how it will affect your ability to use the ACS data? Do you have any ideas on how you want to use ACS data or specific data requests?
You’ve come to the right place. Esri can help you. We have created a Census 2010 and ACS page on our Resource Center. This page includes a link to provide feedback or ask any questions of our Data Development team.

We look forward to hearing from you.
