· The cities in Group IV represent a 50 percent sampling.. Therefore, in order to weight Group IV correctly when computing the percentages in totals for “United States," the number of cities in each column of Group IV bas first been doubled. This procedure has also been followed with other tables related to the second questionnaire when determining the final percentages for geographical regions and for the United States.
