The Digital Divide Among Twitter Users and Its Implications for Social Research

Abstract

Hundreds of papers have been published using Twitter data, but few previous papers report the digital divide among Twitter users. British Twitter users are younger, wealthier, and better educated than other Internet users, who in turn are younger, wealthier, and better educated than the off-line British population. American Twitter users are also younger and wealthier than the rest of the population, but they are not better educated. Twitter users are disproportionately members of elites in both countries. Twitter users also differ from other groups in their online activities and their attitudes. These biases and differences have important implications for research based on Twitter data. The unrepresentative characteristics of Twitter users suggest that Twitter data are not suitable for research where representativeness is important, such as forecasting elections or gaining insight into attitudes, sentiments, or activities of large populations. In general, Twitter data seem to be more suitable for corporate use than for social science research.

The echo chamber is overstated: the moderating effect of political interest and diverse media

“…However, Twitter itself is used by a relatively small proportion of the population, about one-quarter of the UK, which is younger, wealthier, and better-educated than Britain as a whole (Blank, 2017). It is an influential segment, but it is not representative of the British population or British voters.…”

Do Parliamentary Debates of e‐Petitions Enhance Public Engagement With Parliament? An Analysis of Twitter Conversations

“…We explore what Twitter conversations tell us about the ways the public engages with the U.K. Parliament's e‐petitions system, specifically with their debates in parliament, seen as a key step in the petitions’ consideration process. While acknowledging that Twitter data are not representative of the view of the general public (Blank, ; Duggan & Brenner, ; Ruths & Pfeffer, ), we explore them because Twitter is the main tool used by the Petitions Committee to engage the public with parliamentary debates of e‐petitions. However, we also acknowledge that individuals engaged in e‐petition Twitter discussions may not necessarily have signed its respective e‐petition.…”

The empiricist’s challenge: Asking meaningful questions in political science in the age of big data

“…Another issue arises from the fact that the active user base of digital services is not representative of the general population (Blank, 2016;Hargittai, 2015). Again, this might matter little if we are only interested in examining usage patterns on specific digital services.…”
