Online dating may be partially to blame for an increase in income inequality in the US in recent decades, according to a research paper.
Since the emergence of dating apps that allow people to look for a partner based on criteria including education, Americans have increasingly been marrying someone more like themselves. That accounts for about half of the rise in income inequality among households between 1980 and 2020, researchers from the Federal Reserve Banks of Dallas and St. Louis and Haverford College found.

Working Paper 2023-023B by Anton Cheremukhin, Paulina Restrepo-Echavarria, and Antonella Tutino
We examine shifts in the U.S. marriage market, assessing how online dating, demographic changes, and evolving societal norms influence mate choice and broader sorting trends. Using a targeted search model, we analyze mate selection based on factors such as education, age, race, income, and skill. Intriguingly, despite the rise of online dating, preferences, mate choice, and overall sorting patterns showed negligible change from 2008 to 2021. However, a longer historical view from 1960 to 2020 reveals a trend toward preferences for similarity, particularly concerning income, education, and skills. Our findings refute two out of three potential explanations -- reduced search costs and growing spatial segregation -- as potential causes of these long-term shifts. In particular, we conclude that people's capacity to process and evaluate information hasn't improved despite technological advancements. Among the remaining demographic factors, we identify enhanced workforce participation and college attainment among women as the primary drivers of the U.S. marriage market transformation. Furthermore, we find that the corresponding changes in mate preferences and increased assortativeness by skill and education over this timeframe account for about half of the increased income inequality among households. 

Eight Decades of Educational Assortative Mating: A Research Note

Abstract
Recent social and economic trends in the United States, including increasing economic inequality, women's growing educational advantage, and the rise of online dating, have ambiguous implications for patterns of educational homogamy. In this research note, we examine changes in educational assortative mating in the United States over the last eight decades (1940 to 2020) using the U.S. decennial censuses and the American Community Survey, extending and expanding earlier work by Schwartz and Mare. We find that the rise in educational homogamy noted by Schwartz and Mare has not continued. Increases in educational homogamy stalled around 1990 and began reversing in the 2000s. We find a growing tendency for marriages to cross educational boundaries, but a college degree remains the strongest dividing line to intermarriage. A key trend explaining this new pattern is women's increasing tendency to marry men with less education than themselves. If not for this trend, homogamy would have continued increasing until the early 2010s. We also show substantial heterogeneity by race, ethnicity, and nativity and among same- versus different-sex couples.
