THE IMPORTANCE OF NONEMPLOYMENT SOURCES OF INCOME IN CANADIAN METROPOLITAN AREAS*

The use of nonemployment sources of income as a supplement to labor force data in the determination of the urban economic base was investigated for major Canadian cities. It was found that investment and pension-government, the main nonemployment sources, were of increasing importance and that the cities, with one exception, were differentiated into two groups, one based more strongly on investment and the other on pension-government income.
