k 2), 6) all apartment units (n = 216), 7) apartment units with one bedroom (n = 50), 8) apartment units with two bedrooms (n = 117) and 9) apartments with three bedrooms (n = 49) . The eight•coluinns distribute the total number of persons per dwelling unit by age and school status. Pre - school children per unit listed in the first column are not old enough to attend public schools. In the next three columns, children in public schools per unit are assigned by grade, either to elementary school, junior high school or`high school. School -age children attending private schools or receiving schooling at home per unit are listed in the fifth column. The sixth column lists the number of children 18 years old or younger per dwelling unit. Adults per unit, which includes 18 year -olds who are not attending high school, usually because they have begun college, are in the seventh column. The total number of persons per dwelling unit is shown in the final column. Except for rounding errors, the rates are additive. The rates for public - school attendees by grade give the rate of public school attendance. The sum of this rate and the pre- school plus private /home school rates is the average number of children in the units. This rate added to the rate for number of adults gives the number of persons per unit. Exhibit 4 presents the average rates for each cell, which represent the best point estimates for the sample. Exhibit 5 contains the estimates of standard error, which can be used to calculate confidence intervals for each average rate and to test for the significance of differences between single - family and apartment units. The results in Exhibit 4 generally confirm our expectations on the basis of previous surveys. Single- family houses definitely have more persons per unit and more children per unit than apartments. Moreover, these differences are highly statistically significant (t statistic for persons per unit = 7.37, for children per unit = 6.21). The rates for single - family houses are higher than the apartment rates for every category. Therefore, one can say that recent apartment development in urban areas of North Carolina generates less demand for public education and for other demographically - driven public services than single - family housing developed in these urban areas. One major result from the survey is that all apartment units in the sample generate 0.435 persons 18 years old or less compared to 0.975 children from single - family houses.
