Where does old housing stock dominate?

Here’s a nice map of the US by zip code that shows the time period when the plurality of houses had been built. So, a fast growing area did not have most of its housing stock by 1960. Conversely, there are plenty of areas where most of the housing stock was built by 1940 (think Northeast and lots of the plains states).

The data source for this is the American Community Survey. The actual map came from the MapPorn site on reddit.

Two final notes:
This map is based on contemporary information so it doesn’t necessarily really reflect the history of housing stock in a zip code. If housing built in the 1920s was demolished during urban renewal in the 1970s, this stock is no longer available to be reported on by the current residents.

And, just by chance, here’s another image from Reddit on the age of the housing stock by districts in Germany. The dark shades represent either the oldest (purple) or the newest (green).

Census Bureau is on the radar

The Census Bureau is losing its director at the end of this month and due to the pace of political appointments by the administration it could be a long time before it gets a director. This is serious because the Census Bureau is ramping up to the 2020 Census without enough money and was included in the High Risk Report compiled by the Government Accountability Office.

But, instead of focusing on this, Senator Ron Johnson, R-WI noticed that a subcontract for the media campaign has potential political leanings and wants an investigation:

Fox News has learned that last summer, a pro-Democratic analytics firm that describes itself as “a platform for hope and change” was included as a subcontractor in a $415 million advertising contract for the 2020 Census.

The editorial team at Bloomberg News is focused on the big picture:

Avoiding the Census Fiasco of 2020

More is at stake than you might think.

Here are a few snips from this editorial

The fact that the census of 2020 is shaping up to be a fiasco is no small matter.

The troubles at the Census Bureau aren’t new. Nonetheless it falls to President Donald Trump to fix the problem — and to do this, he’ll need to move quickly.

Soon it will be too late to get back on track. Without delay, Trump must nominate competent people to fill the empty posts, and Congress must allocate money for the necessary tests. The census debacle of 2020 is looming.

So, to the nominations or “help wanted” problem:

Here’s a tracking database on the status of political appointments for President Trump. There are a lot of open nominations. In spite of a Trump tweet that Congress is obstructing his appointments, the bigger story is how few nominations there are. As of this post, there was no nominee for 441 of the 559 key positions requiring Senate confirmation. See tracking data base below to check on the status of his appointments.

Census Bureau director resigns

The Census Bureau director has just given notice that he’ll be resigning on June 30, 2017. His term officially ended in December 2016, but he has continued his role as director. This is a crucial time for the Census Bureau as it is ramping up for the 2020 Census without enough funds – at least in historical terms.

Here’s the coverage of John Thompson’s resignation in reverse chronological order:

The U.S. census is in trouble. This is why it’s crucial to what the nation knows about itself
Henry Farrell | Monkey Cage Blog, Washington Post
May 15, 2017

Excellent synopsis of an interview with Ken Prewitt, former Census Bureau director. And, a nice conclusion as well:

President Trump must now step in, name a high-quality director and insist that Congress provide the Census Bureau the money it needs. The 2020 Census will begin in April of that year — right in the middle of primary season. The bureau’s troubles pre-date Mr. Trump’s ascension, but the census is happening on his watch. If it fails, he will own it.

The director resigns just as the $1.5 billion agency heads into its biggest test. Next in command may be a weather forecaster.

The Head of the Census Resigned. It Could Be as Serious as James Comey
Haley Sweetland Edwards | Time
May 12, 2017

In a week dominated by President Trump’s firing of FBI director James Comey, you could be forgiven for missing the imminent departure of another, less prominent federal official.

Yet the news this week that John H. Thompson, the director of the Census Bureau, has abruptly resigned is arguably as consequential to the future of our democracy. That’s because the Census Bureau, while less flashy than the FBI, plays a staggeringly important role in both U.S. elections and an array of state and federal government functions.

Mapping Megaregions via ACS commuting data

Two researchers have created a map of megaregions in the US based on commuting data from the American Community Survey (ACS). The results are covered in both the popular press and in PLOS One. The latter provides more details about how they constructed the maps – it wasn’t just via a mapping program.

White House suggests adding Middle Eastern & North African race category to Census

If approved, the new category would appear on the 2020 Census and could have far-reaching implications for racial identity, anti-discrimination laws and health research. Currently, people from the Middle East are categorized as white: this was the result of a ruling a century ago in which Syrian Americans argued against being in the Asian category and therefore denied citizenship under the 1882 Chinese Exclusion Act. Read more from USA Today: White House wants to add new racial category for Middle Eastern people.

Data Sleuths at the Census Bureau

The Census Bureau gathered data on fertility by asking a “children ever born” question from 1940 to 1990 in the decennial census. The 2000 Census did not ask a fertility question at all. With the advent of the American Community Survey, fertility was covered but with a different question. It asked if a woman had given birth to a child in the past year. This allows researchers to compute a total fertility rate. It performs reasonably well against the measure produced from the vital statistics system. And, given that geography is not readily available with the natality detail files anymore, this is a welcome solution. The main drawback to the ACS question is that the reference year will not span the calendar year that the vital statistics system is based on. Only the December respondents are referencing a January to December calendar year. See the Background section below for a further discussion of this.

However, recently, the Census Bureau noticed some anomalies in the data for selected areas and determined that some interviewers had been sloppy and asked “Have you given birth” rather than “Have you given birth in the last year.” Many more women will answer yes to the former and inflate the numerator. This is a good illustration of how much effort the Census Bureau goes to for producing accurate and robust statistics.

Addressing Data Collection Errors in the Fertility Question in the American Community Survey

August 2016

In recent years, a few geographic areas in the American Community Survey (ACS) data had unusually high percentages of women reported as giving birth in the past year, quite unlike what was seen in previous years for those areas. This paper describes the issue that was discovered, and the measures taken to address it.

Measuring Race and Ethnicity Across the Decades: 1790-2010

The U.S. Census Bureau released a new interactive visualization which shows how race and ethnicity categories have changed since the first census.

From the Random Samplings blog post:

Over the years, the U.S. Census Bureau has collected information on race and ethnicity. The census form has always reflected changes in society, and shifts have occurred in the way the Census Bureau classifies race and ethnicity. Historically, the changes have been influenced by social, political and economic factors including emancipation, immigration and civil rights. Today, the Census Bureau collects race and ethnic data according to U.S. Office of Management and Budget guidelines, and these data are based on self-identification.

Changing Race From One Census to the Next

Via D’Vera Cohn, Pew Research Center, FactTank

Millions of Americans counted in the 2000 census changed their race or Hispanic-origin categories when they filled out their 2010 census forms, according to new research presented at the annual Population Association of America meeting last week. Hispanics, Americans of mixed race, American Indians and Pacific Islanders were among those most likely to check different boxes from one census to the next.

Census Bureau Estimates, 2011

The Census Bureau released estimates of places in late June.

Data

Note that these estimates use a different algorithm than the state/county population estimates released earlier this year. Estimates for places are based on housing unit methodology. The estimates for states and counties are based on vital statistics (births, deaths) and an estimate of migration.

This makes a difference if one is comparing Detroit or Cleveland, which are both sub-county population estimates as compared to Baltimore, which is a county equivalent.

The results for Michigan show Detroit losing 3% of its population and remaining just above 700,000. All other places within Wayne County have very similar rates – with most of the difference due to the variations in the distribution of the GQ and household populations across these communities.

On the other hand, the Population Estimates for places produced by the Southeastern Michigan Census Council (SEMCOG) show quite a bit of variation within counties. Hamtramck grew by 2.1%, while Detroit and Highland Park declined by 4% and 6.6% respectively.

And, big picture-wise, Texas is home to 8 of the 15 most rapidly growing cities. [Press Release]
