Influ of People: New York City

Manhattan is the heart of New York, and on an average workday it plays host to 3.94 million people. All the other boroughs of New York experience a net population loss. Unfortunately, the last census was in 2010, it is due this year, but this is the most recent available data. Regardless, the influx of people into New York each day is over three times that of its closest city. The numbers reveal some interesting trends around the habits of New Yorkers.

  • Based on numbers from the last census, on weekdays, Manhattan has a population comprising 778,000 visitors, 1.61 million commuting workers, 70,054 commuting students, 18,236 hospital users, and 1.46 million local residents, for a total of 3.94 million.

Research Strategy

We reviewed the data from the last US Census in the hope it might include data around the influx of people into New York. The available data was substantial but would have required hours of analysis to make broad generalizations at best. Information regarding the population of New York was available and grouped by Borough.

Next, we reviewed a range of industry publications to locate any studies or reports that might have discussed the influx of people into New York. One report from 2012, based on the analysis of the US Census data, provided some pertinent details. The information was not based on the hourly influx, but it did contain information about the daily influx. We had some concerns, given that it is eight years old. However, a range of different resources confirmed this to be the most recent data. We have provided a comprehensive summary.

Our third strategy saw us review relevant media articles, government statements, and information from the local administration. Media articles often contain details of studies, government policy, briefings, and different trends. We hoped that there would be a reference to the number of people entering New York. We located a couple of articles reporting that a graphic had been created showing movement by the hour. Unfortunately, when we reviewed the graphic, it was mostly for visual effect and the hourly influx could not be extrapolated. We attempted to trace the data used to the source as it contained the key information. Unfortunately, this information is not in the public domain.

The data we have presented focuses mostly on Manhattan as that sees the most significant influx, and for many is New York. We have also provided details of the other Boroughs
