On the "What is a household" page, the link at the bottom of the page which enables you to get to "How do I participate in the 1950 US Census Document Header Review" does not connect. The other two links work.
@MerilynGreen, the reason that the link does not work is because we have finished the Header Review the article is not necessary anymore. They have disabled the article. So sorry for the frustration. We hope that this answers your question.
We now only have the Family Review to do. Thank you for all that you do.
