City/Place Daytime Population
The most current data on city, county, state daytime population is located at http://proximityone.com/daytime_population.htm. The concept of the daytime population refers to the number of people who are present in an area during normal business hours, including workers. This is 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 populations is important for many planning purposes, including those dealing with market size, trade/service areas, transportation, disaster, and relief operations. Use the interactive ranking table below to examine cities and patterns of interest. The table shows places as of Census 2000 with either 2,500 workers living in the place or 2,500 workers working in the place. Employment-Residence (E-R) The far right column (see description of all columns below table) shows the Employment-Residence (E-R) ratio. The E-R Ratio is a measure of the total number of workers working in a place (WorkersWP), relative to the total number of workers living in the place (WorkersLP). The E-R Ratio is a rough indicator of the jobs-workers balance in a place, although it does not take into account whether the resident workers possess the skills needed for the jobs that are available. E-R Ratios greater than 1.00 occur when there are more workers working in the place than living there. These places can be considered as net importers of labor. City-Place Daytime Population See related Ranking Tables Main Page Click column header to sort; click again to sort other direction. Workers defined. People 16 years and over who were employed and at work during the reference week. The estimate of workers includes part-time and full-time civilian personnel and people in the Armed Forces. Daytime population universe. The daytime population estimates in the table adjusts only for work-related travel, i.e., incommuters to an area and outcommuters from an area. Data necessary to adjust for shopping, school, recreation, tourism, etc. are not available. These daytime population estimates are developed by the Census Bureau.

Columns: Population -- Total resident population the total number of persons living in the place, as shown in Census 2000 100-percent data such as Summary File 1. WorkersWP -- Total workers working in the place this is the number of workers who reported working in the place, regardless of their place of residence. In other words, it is the total that worked there no matter where they lived. Residence locations are not considered, only workplace locations are reflected in this number. WorkersLP -- Total workers living in the place this is sometimes referred to as the number of resident workers. It is the number of people living in the place who are workers. It includes workers who live there regardless of where they worked, or in other words, no matter where their workplace was located. Place of work location is not considered, only residence location is reflected in this number. Daytime -- Estimated daytime population this is the estimate arrived at by adjusting the total resident population by the number of incommuters and outcommuters to the place, using data from Census 2000. It does not adjust for people entering or leaving the place for purposes other than commuting, nor does the commuting adjustment take the time of day of the work trips into account. The estimate is calculated by adding the total resident population (Population) and the total workers working in the place (WorkersWP), and then subtracting from that result the total workers living in the place (WorkersLP). This method yields the same result as would be obtained by adding the incommuters and subtracting the outcommuters from the total resident population. Daytime1 -- Daytime population change due to commuting: number this is the numeric increase or decrease in the population of the place as a result of work-related commuting. It is the net change in the population due to work travel and is computed by subtracting the total resident population (Population) from the estimated daytime population (Daytime). Positive numbers indicate more commuters entering the place than leaving it. Negative numbers occur when more workers leave the place to go to work than enter it to come to work. %Daytime1 -- Daytime population change due to commuting: percent this is the percentage increase or decrease in the population of the place as a result of work-related commuting. It is calculated by dividing the numeric change due to commuting (Daytime1) by the total resident population (Population), and multiplying the result by 100. Positive figures denote the percentage increase experienced by the population, while negative numbers show the percentage decrease in the population as a result of commuting. WorkersLW -- Workers who lived and worked in the same place: number this value shows how many workers who lived in a particular place also worked in that same place. It is derived from place of residence location information and responses to the question on workplace location during the week prior to filling out the census questionnaire. %WorkersLW -- Workers who lived and worked in the same place: percent this measure is sometimes used as an indicator of worker retention, but it does not reflect variation in area size or other attributes very well. It is computed by dividing the number of workers who lived and worked in the same place (WorkersLW) by the total workers living there (WorkersLP) and multiplying the result by 100. ER Ratio-- Employment-residence (E-R) ratio this is a measure of the total number of workers working in a place (WorkersWP), relative to the total number of workers living in the place (WorkersLP). It is often used as a rough indication of the jobs-workers balance in a place, although it does not take into account whether the resident workers possess the skills needed for the jobs that are available. E-R ratios greater than 1.00 occur when there are more workers working in the place than living there. These places can be considered as net importers of labor. For example, an E-R ratio of 1.19 means that there are 19 percent more workers working in the place than living in the place. Values less than 1.00 indicate places that send more workers to other areas than they receive, i.e., they are net exporters of labor.
