I have found the data set for types of computers in household by state, see here: https://data.census.gov/cedsci/table?q=Computer%20Type&g=0100000US.04000.001&tid=ACSDT1Y2019.B28001&hidePreview=true&moe=false&tp=false But cannot segment by age groups current ACS has the following 3: "Under 18 years" ,"18 to 64 years", "65 years and over". Can this be queried via the API or by other means?
The variables you'll need from PUMS to construct these estimates are AGEP, COMPOTHX, LAPTOP, SMARTPHONE, and TABLET. Once you pull the microdata, you'll need to create the age groups you are interested…
For reference, This is what I would like https://data.census.gov/cedsci/table?q=Computer&g=0100000US.04000.001&tid=ACSDT1Y2018.B28005&hidePreview=true for table B28001.
