In the years 1907, 1957 and 2007 in the U.S., which was) the percentage of households with bath 2) percent of households telephone. 1 3) the number of cars 4) the number of miles of highways 5) the maximum speed limit in most cities 6) structure highest in the world 7) the average wage in the United States the average income per year 9) percent of Americans graduate from high school. If you know the answers, even a few, please help me. Thank you very much.

I do not know exactly, but if I were to say, I think http://www.census.gov would be the best resource for start. Office of the U.S. Census collects data like this every 10 years.
