> relevant survey data
Based on a cursory look, keywords can include "smartphone-only internet users" and "large-screen computer ownership".
The American Community Survey asks questions related to that (income, computing devices). Comparing states, the poorer the residents of a state, the smaller the percent of households with regular computers ("large-screen computer ownership"), per "Computer Ownership and the Digital Divide" (Mihaylova and Whitacre, 2025) [0, 1, 2].
Also, Pew runs surveys on income and device usage ("smartphone-only"). Again, the lower the income, the higher the proportion that is smartphone-only [3, 4].
