Washington, D.C., Has Huge Increase | |||
Census Bureau Releases First-Ever Data |
|||
If it seems a little crowded on weekdays in cities like Washington, D.C.; Irvine, Calif.; Salt Lake City, Utah; or Orlando, Fla.; it’s not your imagination. Among cities with 100,000 or more people, these four show the highest percentage increases in population during the day as opposed to their resident population. The findings come from the first-ever U.S. Census Bureau estimates of the daytime population for all counties and more than 6,400 places across the country, based on Census 2000 data. The concept of the daytime population refers to the number of people, including workers, who are present in an area during normal business hours, in contrast to the resident population present during the evening and nighttime hours. “Information on the expansion or contraction experienced by different communities between nighttime and daytime is important for many planning purposes, including those dealing with transportation and disaster relief operations,” said Census Bureau Director Louis Kincannon. “By providing information on the number of people not living in the area, but nevertheless greatly affected by the event, the data can provide a clearer picture of the effects of disasters such as Hurricanes Katrina and Rita.” The places where the largest percent increases in daytime over nighttime populations occur tend to be those with small resident populations. For example, among medium-sized cities, Greenville, S.C., has a daytime population that is 97 percent higher than its nighttime population. Palo Alto, Calif., increases by about 81 percent, and Troy, Mich., by 79 percent. Among very small places, gains approached 300 percent in Tysons Corner, Va. (292 percent); and El Segundo, Calif. (288 percent). (See Table 1.) Other highlights:
