[CTPP] Christian Science Monitor article

The Christian Science Monitor article (http://www.csmonitor.com/2002/0531/p01s01-ussc.html) included: "The change [increase in commute time], while it may stem in part from new data-gathering methods, is significant." Is the change in the range for long commutes the only change that was made in "data-gathering methods"? (What was the change in the range for long commutes (someone said the 1990 high-end range was 99+ minutes)? Since the 1990 long form simply asked how long, in minutes, is the commute (ie no ranges were included on the form), why didn't the Bureau just add up the total travel time and divide by the number of respondents?) Considering the fact that the total population of North Dakota did not change in the 1990's, I doubt that the actual rise in average commuting time was any where near the reported 22%. Rob Robert B.
