The most densely populated place in the United States, as of April 1, 2010, is Friendship Heights Village (a Census Designated Place, or CDP), in Maryland. Friendship Heights is a small, 38 acre neighborhood on the border of the District of Columbia. Population = 4,698; Area = 0.059 square miles; Density = 79,627 persons per square mile (ppsm).
Mark Twain was born in the village of Florida, Missouri, in 1835. He’s more closely associated with Hannibal, Missouri, the town that inspired Tom Sawyer and Huckleberry Finn. Twain and his family moved to Hannibal when he was four.
The population of Florida, Missouri, is zero people according to the 2010 Census. That’s right, a place/city/town/village with zero/nil/goose egg population. Florida is tied with 19 other places for the “least populated places in the United States.” Mark Twain once said that Florida, Missouri was “a nearly invisible village.” Now, it’s basically the home to the Mark Twain Birthplace State Historic Site.
This blog post is probably the first of several related to health insurance in the United States. The US Census Bureau has an amazing array of data related to health and health insurance, and I’m just trying to see what is available, what are the trends, and what are the characteristics of the insured and the not-insured.
The most recent and key report summarizing health insurance coverage is the US Census Bureau Report P60-257: “Health Insurance Coverage in the United States: 2015” (published September 2016) available on this Census Bureau web page. https://www.census.gov/library/publications/2016/demo/p60-257.html. It’s a must read for anyone interested in health insurance, the health care debate, and the Affordable Care Act.
Here is a graphic from this report which shows the uninsured rate by detailed age, and how it’s changed between 2013 and 2015:
I have updated my race/ethnicity diversity blog posts to include the spreadsheet workbooks (large cities, 65,000+, Congressional Districts).
Also, I updated the spreadsheet workbooks for the Bay Area Congress blog post.
I use Apple Numbers as my spreadsheet software. I then export Excel files from Numbers. I hope this is of use!

How many people live in the average US Congressional District? Well, it all depends. As of April 1, 2010, there were 308,745,538 persons living in the 50 United States and the District of Columbia. Less the 601,723 people living in DC, there are 308,154,815 persons in the 50 states. This number, divided by 435 house seats, yields 708,376.6 persons per average Congressional District.
So, how does the total population vary, state-by-state? This can be tricky since the early results from Census 2010 are tabulated at the “old, Census 2000-based congressional districts.” And, as all citizens should know, the primary purpose of the decennial census is to reapportion and redistrict the boundaries of congressional house seats!
The most racially/ethnically diverse congressional district in the United States, in 2015, is the 13th District in California. It is represented by Barbara Lee (D-Oakland) and comprises the cities of Oakland, Berkeley, San Leandro, Alameda, etc., in the East Bay of the San Francisco Bay Area. This is based on data from the 2015 American Community Survey conducted by the US Census Bureau.
Here is a graphic showing the 10 most racially diverse congressional districts in 2015:
The least racially/ethnically diverse large city in the United States, in 2015, is Springfield, Missouri. This is based on 2015 data from the US Census Bureau’s American Community Survey (ACS).
The top five large cities are
Here is a table showing the 25 large cities ranked on lowest racial/ethnic diversity index:
The most racially/ethnically diverse large city in the United States, in 2015, is Vallejo, California. This is based on 2015 data from the US Census Bureau’s American Community Survey (ACS).
Oakland, California is the second most racially diverse large city in the United States, followed by Jersey City, New Jersey; Fairfield, California; and Sacramento, California.
If we use a cutoff of 250,000-or-more population, then the most racially/ethnically diverse “very large USA cities” would be #1: Oakland, #2: Jersey City, #3: Sacramento, #4: New York City, and #5: Stockton, California.

In yesterday’s blog post, I mentioned “Table B23001” from the American Community Survey (ACS), using the US Census Bureau’s American FactFinder (AFF).
So, what is the significance of the table number “B23001”? Do you need a secret decoder ring to figure this out? (Yes, in fact, you do!)
There is a secretive FAQ page (Frequently Asked Questions) on the US Census Bureau website that explains the ACS table numbering schemes. It’s here.
