Housing Starts Exercises 43–48 are based on the following table, which shows the number of new (single-unit) houses started, in thousands, in the different regions of the United States during 2012–2014.8 Take S to be the set of all housing starts represented in the table, and label the sets representing the housing starts in each row and column as shown (so, for example, N is the set of all housing starts in the Northeast during 2012–2014).
