Work Day Population Increases Across the U.S.


 

On the average work day, Manhattan’s population increases by nearly 1.5 million people. See the chart below for the top 10 workday population increases in counties across the United States.

This chart is part of our report, “The Dynamic Population of Manhattan,” which analyzes the volume of people flowing in and out of Manhattan during a 24-hour period. Click here for the full report.

The Super-Commuter and Transportation Policy


By Carson Qing

In our recently released super-commuter study, we defined a potential super-commuter as an individual who works in the core county of one metropolitan labor market, but lives in another metropolitan area, based on data from the U.S. Census Bureau’s OnTheMap tool. Using these definitions, super-commuters may include individuals who commute daily, weekly, monthly, or may not even commute at all, working remotely. Below is a chart of the most common super-commutes in the United States.

The Arizona Sun Corridor is the most prominent super-commute corridor in the nation, based on the 10 core counties of the largest metropolitan labor markets. Residents from the Tucson area commuting to the Phoenix area (Maricopa County) account for 3.6% of the latter’s workforce, or 54,400 total. Robert Lang and Arthur Nelson have conducted extensive research on the growing convergence between metropolitan regions, and first coined the term “Sun Corridor,” which they predict will become the next Dallas-Fort Worth, merging into a mega-region of 9 million people over the next few decades.

Transportation planners in Arizona are already quite familiar with the impact of that super-commutes are having along the Sun Corridor. Arizona DOT planners estimate that already lengthy super-commutes on Interstate 10 between Tucson and Phoenix would take more than twice as long in 2050 due to a doubling in travel demand, even if the road were to be widened, primarily due to population and economic growth, as well as the already substantial volume of daily commutes between the two cities. Consequently, DOT officials are in the early stages of studying the impact of a multi-billion dollar intercity passenger rail line connecting the two cities in anticipation of the mega-region’s emergence and to sustain its current economic and demographic growth. Establishing a rail corridor may allow land use planners to shape development patterns in a way that e  nhances mobility between the regions and further alleviates the anticipated traffic congestion along the I-10 corridor. The Phoenix-Tucson rail initiative exemplifies how the emergence of the super-commuter during the past decade is already making a significant and important impact in regional transportation policy. On Thursday, I will discuss what the private sector has already done to facilitate these super-commutes nationwide.

New Report: The Dynamic Population of Manhattan


 

In our new report, we look at the 24-hour flow of people into Manhattan, including the 1.6 million commuters who enter Manhattan every weekday, and the hundreds of thousands of visitors who use Manhattan’s tourist attractions, hospitals, universities, and nightclubs. This island, measuring just 22.96 square miles, serves approximately 4 million people on a typical weekday, 2.9 million on a weekend day, and a weekday night population of 2.05 million. Manhattan, with a residential population of 1.6 million, more than doubles its daytime population as a result of the complex network of tunnels, bridges, railroad lines, subways, commuter rail, ferry systems, bicycle lanes, and pedestrian walkways that link Manhattan to the surrounding counties, cities and towns.

This report analyzes the volume of people flowing in and out of Manhattan during a 24-hour period; we provide an upper estimate of the actual number of people in Manhattan during a typical work day.
