NOTES FOR 1970 VASHON-MAURY ISLAND FEDERAL CENSUS DATA

 

This file presents summary information from the 1970 U.S. Census for Vashon-Maury Island.  What is offered is for all of Vashon-Maury Island, identified as the Vashon Island Division.  More 1970 Census data may be available than is provided on the table included in this website.

In 1970, the Census reference day was April 1, 1970.  For this survey, the Census Bureau mailed out Census questionnaires which allowed those responding to self-report information.  Approximately 60% of the U.S. population living in urban areas were asked to mail back their completed forms.  The other 40% were asked to hold onto their completed forms for pick-up by a Census Enumerator.  It is assumed Vashon-Maury Island fell into the latter group.    

At some point after the 1940 Census, the Bureau instituted a system which sub-divided geographic areas into Census Tracts, however, these were defined as having a minimum population of 3000.  In 1970, Vashon-Maury Island barely met this standard.  Additionally, at some point, the Census Bureau initiated a system of smaller geographic sub-divisions titled Census Blocks.  The standard for these was at least 100 people, and the geographical areas were defined by street names.  It is unknown whether Vashon-Maury Island was sub-divided into Census Blocks, and if so, whether the Census Bureau provided information for these geographic areas.  As of February, 2014, further research is underway to answer these questions.  If additional detailed data for Vashon-Maury Island from the 1970 Census can be located, it will be provided on this Census Project website.
