I am looking for information on the number of households in each county that used natural gas in 1940 and 1950. The variable FUELHEAT has this information from 1960 onwards, specifically with the value code 2 (‘Utility gas from underground pipes serving neighborhood’). According to the Census Bureau the “home heating fuel question originated with the 1940 Census.” However, this variable is not available in the 1940 and 1950 Census microdata available on IPUMS.
I’m wondering whether perhaps there are plans for this 1940 and 1950 data to become availalable on IPUMS in the future, or if there is another source that this information could be accessed?
Thank you in advance for the help!
