What journey-to-work data is available from the 1970 Census?
MTC has the 1970 Census commuter matrices at the old 440 zone and old 550 zone levels. We’ve also aggregated these zone-to-zone commuter matrices to the MTC 34 superdistrict and nine county level. The superdistrict-to-superdistrict and county-to-county data are published on the MTC CTPP web page. The 440-to-440 and 550-to-550 zone data files can be provided on request, but we do not have GIS layers to support these old zone systems. Place-to-place commuter data is only available from the 1980-2000 Censuses. Means of transportation to work included in the 1970 Census include: vehicle driver, vehicle passenger, bus or streetcar, subway or elevated, railroad, taxicab, walk only, worked at home and other means.
