The carpool usage for commuting to work in the US has demonstrated minimal fluctuations from 2013 to 2019, maintaining a nearly stable volume of around 13.38 million units. However, 2020 saw a significant drop by 17.02% to 11.1 million units, largely attributed to the COVID-19 pandemic and its impact on commuting patterns. A recovery was observed in 2021 with a 14.43% increase, followed by a steady restoration to 13.36 million units in 2023. The Compound Annual Growth Rate (CAGR) over the past five years showed a marginal negative trend, standing at -0.022% as of 2023. Forecasts indicate a slight decline to 13.31 million units by 2028.

Future trends to monitor include:

Impact of telecommuting and hybrid work models on commuting behavior.
Rise of environmentally conscious commuting options and their effect on carpooling popularity.
Technological advancements in ride-sharing and their potential integration with carpool systems.
