Commuter -adjusted population indicates that where the jobs are and which communities do little more than give people to sleep. As a major job center Manhattan has one of the most dramatic changes in the daytime population.The latest report reveals that 1.5 million people live in Manhattan which is larger than the population of Dallas,Phoneix and San Franscisco. Percentage-wise, though, the growth of Redmond City, Washington, is even greater; the population of the Seattle suburb expands by about 111 percent by day.These figures come from a new report from the Census Bureau using data from the American Community Survey, which asks people both where they live and work in selected 20 cities across the nation. Those cities that lose the most population by day tend to be outer-ring suburbs with lots of homes and few jobs.
