After you have transcribed and analyzed the information, take the names of neighbors from the census and ask family members if they remember people with those names. Names of neighbors can often jog people's memories and cause them to remember stories you never thought to ask. That's one thing I wish I had done with my grandfather's 1930 census entry for the rural township in Illinois where he grew up. I'm certain asking about those names from the nearby census entries would have generated a lot of memories.
When the 1940 census comes out and you finally find your people, don't just file the information away. Use it.
