The Sixteenth Census of the United States was released to the public in April, 2012. The Cowlitz Co., WA Census can be found online at the National Archives. The census date was April 1, 1940. No index is yet available.

Since the images are freely available online, I have begun to create an every-name index. If you would like to contribute to the indexing effort, I would welcome your help. Please email to Jenny Tenlen for more information.

The 1940 population of Lewis Co. was 41,393.

(Note: all population data was taken from the National Archives record at the link above.)
