An exclusive Axios/SurveyMonkey poll reveals that income strongly affects how Americans access the internet, and the divide cuts across geography.

• In both urban and rural areas, exactly half of the lower income population reported having broadband internet at home — the lowest percentage of any group.

Our research also found that income was a strong factor in determining why a person might rely primarily on a smartphone for internet access.

• Members of families making less than $50,000 per year were more likely than higher-income respondents to say they use a smartphone because they didn't own a computer or because it was cheaper.
