The Canadian city, for example, is more compact

 than its United States counterpart of equal population

 size, with a higher density of buildings and people

 and a lesser degree of suburbanization of populations

 and functions.  Space-saving, multiple-family housing

 units are more the rule in Canada, so a similar

 population is housed on a smaller land area with

 much higher densities, on average, within the central

 area of cities.  The Canadian city is better served

 by and more dependent on mass transportation

 than is the United States city.  This dependence

 gives form and structure to the Canadian central

 city, qualities now lost in the sprawling United States

 metropolis, whose residents view the central district as

 increasingly less central to their lives.  Since
                Canadian

 metropolitan areas have only one-

 quarter the number of kilometers of superhighways

 per capita as United States metropolitan areas ---and

 at least as much resistance to constructing more --

 suburbanization of peoples and functions is less

 extensive north of the border than south.  It is likely

 to remain that way.
