Today, the U.S. Census Bureau released an updated version of the population clock, one of the most widely visited features on the census.gov website. The enhanced clock provides the public with a quick and interactive overview of the population in the United States and the world, and now it also can be shared, downloaded and embedded on other websites. This release coincides with the beginning of the Population Association of America's annual meeting in New Orleans.
"As part of the celebration of 2013 as the International Year of Statistics, the Census Bureau is celebrating the role of statistics in everyday life through new, interactive and easily accessible data tools such as the population clock," said Victoria Velkoff, the assistant division chief in charge of estimates and projections in the Census Bureau's Population Division. "The introduction of the updated 'pop clock' will further broaden the public's appreciation for and grasp of population statistics."
The population clock displays continuously updated projections of the total U.S. population, including the rate of births, deaths and net migration for the United States. For the first time, the clock also provides an age and sex population pyramid and a graph showing the population of U.S. regions. Both new features allow users to see how these measures have changed over time. Additionally, users can interact with tables displaying the most populous states, cities and counties in the United States. The clock provides not only a continuously updated world population total but also a list of the 10 most populous countries, with easy access to more world population statistics.
An important enhancement allows users to embed the population clock on their own website for quick reference. Using the "Download and Share" buttons, users can download the clock or copy code to embed the clock directly on their own website. Visitors can also share the clock via Facebook, Twitter or Pinterest.
The clock is based on a series of short-term projections for the resident population of the United States. This includes people whose usual residence is in the 50 states and the District of Columbia. These projections do not include members of the armed forces stationed overseas, their dependents, or other U.S. citizens residing outside the United States.
The projections are based on a monthly time series of population estimates starting with the April 1, 2010, resident population count derived from the 2010 Census.
The "Country Ranking" tool provides a quick and easy method to view the most populous countries in the world for any given year. The data for this tool are drawn from the Census Bureau's International Data Base, which offers a variety of demographic indicators for countries and areas of the world with a population of 5,000 or more.
