it would be helpful before tossing out all the census data (ie the baby with the bath
water) to know what the
numbers are. what are the local numbers? how are they derived? there could be dozens of
legitimate reasons why
two sets of numbers do not agree. the census is very open in reporting what it is that is
being counted and
how. without knowing all sides of the story makes it difficult for any reasonable analysis
to take place.

Census Data on Traffic Questioned
By Scott Martelle and Dan Weikel
Times Staff Writers
March 9, 2003
Southern California planners and demographers are questioning census data on the
region's commuting
patterns released last week -- a concern that hints at broader problems with some census
estimates.
The numbers released Thursday counted residents by where they live and work to measure
commuting patterns.
They were derived from data collected in the 2000 census long form, an extensive
questionnaire filled out
by about one of every six households in the country.
The data indicated a continuing and dramatic decrease in the number of people commuting
to Los Angeles
from surrounding counties -- an erosion of Los Angeles' decades-long standing as the
region's economic
heart.
While the trend toward increased economic independence in Orange, Riverside, San
Bernardino and Ventura
counties is unquestioned, census estimates of employment levels and commuter patterns
conflict sharply
with established jobs surveys and regional transportation studies.
The question confronting demographers now is, if census conclusions about Southern
California employment
and commuter patterns are wrong, what other census conclusions are off kilter?
