About this dataset

Context

The dataset tabulates the District of Columbia population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of District of Columbia across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2023, the population of District of Columbia was 678,972, a 1.20% increase year-by-year from 2022. Previously, in 2022, District of Columbia population was 670,949, an increase of 0.29% compared to a population of 669,037 in 2021. Over the last 20 plus years, between 2000 and 2023, population of District of Columbia increased by 107,196. In this period, the peak population was 708,253 in the year 2019. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).

The District of Columbia is the only non-state entity of the United States with a share of electoral votes in U.S. presidential elections. Since the 23rd Amendment to the U.S. Constitution granted Washington D.C. representation in these elections, the nation's capital has had three electoral votes in each election since 1964. In these 16 elections, Washington D.C.'s citizens have chosen the overall winner seven times, giving a success rate of 44 percent, which is the lowest in the country. As of 2024, no U.S. president has ever been born in Washington D.C., although former Vice President and Democratic nominee in the 2000 election, Al Gore, is the only major party candidate to have been born there, during his father's term in the House of Representatives. Always Democratic The District of Columbia has voted for the Democratic Party's nominee in every presidential election that has been contested in the capital. Not only do Democratic nominees perform well in D.C., they win these electoral votes by significant margins; Democrats have won over ninety percent of D.C.'s popular vote in the past four elections, and the worst performance ever by a Democrat was in 1980, where Jimmy Carter only won 75 percent of the popular vote. Factors such as heavy urbanization and ethnic diversity are generally cited as the reasons for D.C.'s strong Democrat voter base. Fifty-first state? The only time when a Democratic nominee did not receive all three electoral votes was in 2000, when one elector abstained from casting her ballot, as a protest of D.C.'s lack of voting representation in Congress. While the District of Columbia can take part in presidential elections, it is a federal district under Congress' jurisdiction, and does not have voting representation in either chamber of Congress. The statehood movement aims to make Washington D.C. the newest state to join the union, possibly under the name "New Columbia" or "Washington, Douglass Commonwealth" (named after the abolitionist, Frederick Douglass), and bring an end to what it sees as "taxation without representation". Generally speaking, lawmakers are split along party lines on whether D.C. should receive statehood or not; with Democrats in favor of the proposition, while Republicans are opposed to the idea (as it would likely bolster the Democrat's numbers in Congress). A survey conducted in June 2020, showed that roughly 40 percent of registered voters support the idea of D.C. statehood, while 41 percent oppose the idea, and the remainder are undecided; the topic gained renewed attention in 2020 when President Trump used the capital's National Guard to disperse peaceful protesters from near the White House during the George Floyd protests.

About this dataset

Context

The dataset tabulates the District of Columbia population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of District of Columbia across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2022, the population of District of Columbia was 671,803, a 0.45% increase year-by-year from 2021. Previously, in 2021, District of Columbia population was 668,791, a decline of 0.31% compared to a population of 670,868 in 2020. Over the last 20 plus years, between 2000 and 2022, population of District of Columbia increased by 100,027. In this period, the peak population was 708,253 in the year 2019. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).

Over the past two years, the District has expanded its housing voucher program for people experiencing chronic homelessness by more than 100%. For the first time, ending chronic homelessness is in sight. Still though, the process of getting vouchers to the people who need them is complicated and time-consuming. This page tries to make sense of the process, and create greater visibility into our progress so far, and the continued challenges we face.

The sources of disease surveillance information include contact tracing, medical record review, and laboratory information, and are considered protected health information. When interpreting the results of these analyses, it is important to keep in mind that the disease surveillance system may not capture the full picture of the outbreak, and that previously reported data may change over time as it undergoes data quality review or as additional information is added. These analyses, especially within populations with small samples, may be subject to large amounts of variation from day to day. Despite these limitations, data from disease surveillance is a valuable source of information to understand how to stop the spread of COVID19.
