Hi, I am Alexandra Barker.
Do you know how diverse your state is?
I often get questions from data users about diversity
in the United States.
The Census Bureau uses a diversity index
to measure the probability that two people chosen at random in a given area, will be from different race and ethnicity.
So for this Data Gem,
I asked my colleague Megan Rabe
to show us how to access data
for race and ethnic diversity from 2010 and 2020
using a data visualization.
This is a unique way to identify trends for your state and county.
So, let’s learn about this resource with Megan.
Hi, I’m Megan Rabe.
I’m a demographer and visualization developer in the Population Division at the Census Bureau.
Today,
I’m thrilled to show you how you can use our data visualization
to learn about racial and ethnic diversity in 2010 and 2020.
You can find the Racial and Ethnic Diversity in the U.S. visualization on census.gov
in the Infographic & Visualization library or by clicking on the link above or in the description of this video.
I’m going to click on the “full screen” button on the bottom of the page,
to make the data viz a little bit bigger.
This visualization has four sections:
Diversity Index Maps,
Race and Ethnicity Prevalence Rankings,
Race and Ethnicity Prevalence Maps,
and Data Tables.
The current selection is the Diversity Index Maps.
As Alexandra explained in the beginning of this data gem,
we use the diversity index to measure the probability
that two people chosen at random will be from different race and ethnicity groups.
In 2020,
that was a 61.1% chance in the United States.
For more information about calculating the diversity index,
hover over the note at the bottom of the page.
The map shows the diversity index in 2020.
Hovering over a state shows the distribution of racial and ethnic groups.
Clicking on a state in the map will highlight it in the rank chart.
Here we can see Nevada had the
3rd highest diversity index in 2020.
You can also change the filter to view the data for 2010.
To find information for your county, use the filter on the right to select a state,
DC, or Puerto Rico
Let’s choose Nevada
and click the arrow.
Now we can see that Clark County had the highest diversity index within the state
at 72.0%,
meaning that there was a 72.0% chance that two people selected at random within the county
be from different racial or ethnic groups.
Here, we can also highlight a county
change the state,
or return to the national view.
Race and Ethnicity Prevalence Rankings are next.
Prevalence ranking graphs show the percentage of the population that fall into the largest racial or ethnic group,
second largest racial or ethnic group,
or third largest racial or ethnic group.
The diffusion score measures the percentage of the population that is not in the first, second,
or third largest racial or ethnic group.
You can change the year to see differences between 2010
and 2020.
Like before,
change the state
and click the arrow
to view the same data at the county level.
Next, are the Race and Ethnicity Prevalence Maps.
Prevalence maps show the geographic distribution of the largest,
second largest, or third largest racial or ethnic group at a specific geographic level.
You can zoom on the map
using the plus and minus signs in the left corner.
Click the home button to return to the original view.
The filters on the right allow you to highlight a county
or a racial or ethnic group.
Maps are available for 2020 and 2010
Along with being available for the largest racial group,
second largest or third largest racial or ethnic group.
and third largest ethnic group.
The table shows
the number and percentage of U.S. counties based on your selection.
The last section allows you to see the data in a table format.
This includes county ranking for both 2020 and 2010.
Change the filters at the top
and click the arrow to update the tables.
I hope you enjoy using this visualization to explore racial and ethnic diversity for your state and county.
Megan, this is a very interesting resource.
Thank you for sharing with us.
