NOTES FOR 1980 VASHON-MAURY ISLAND FEDERAL CENSUS DATA
This file presents summary information from the 1980 U.S. Census for Vashon-Maury Island. More 1980 Census data are available than is provided on the table included in this website.
What is offered here is for all of Vashon-Maury Island, identified as the Vashon Island Division, and for two separate geographic areas identified as Census Tracts numbered: 277.01 (north end of the Island) and 277.02 (south end of the Island). The standard for a Census Tract is that it contain a population of approximately 3000. The geographic boundary line between these two Census Tracts was as follows: from the west side of the Island going east – SW 220th St, to 11th Ave SW going north, to 204th Ave SW going to the east side of the Island. Everything north of this line was part of Census Tract 277.01 and everything going south was in Census Tract 277.02.
In 1980, the Census reference day was April 1, 1980. For this survey, the Census Bureau mailed out Census questionnaires which allowed those responding to self-report information. They were then instructed to mail back the completed forms. In some rural areas where postal service may not have been as complete, Census Enumerators hand-delivered Census questionnaires four days before the official Census Day and then returned to pick up completed forms. It is not known if Vashon-Maury Island fell into the latter group.
At some point, the Census Bureau initiated a system of even 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 for 1980, 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 1980 Census can be located, it will be provided on this Census Project website.
