MyHeritage has just released a free tool called The Census Helper™, a great facility that scans your tree and automatically compiles a list of individuals appearing in it who are very likely to be found in the 1950 U.S. census, along with relevant details. Armed with this list, you’ll know exactly which family members to search for in the newly released records, and your research will be much more focused. You’ll also be able to research those individuals in the census records with the click of a button.
It also provides the facility to produce a list of people in your tree who are likely to be included in every other census, from 1790 through 1940.
I encourage that if you don't have a tree on MyHeritage to upload it as a GEDCOM and use this tool for free, so they can get a head start on your 1950 census research. You can do so via this landing page.
You can learn more about the Census Helper™ in the MyHeritage blog post, and feel free to spread the word.
