Over time, Congress has slowly become more reflective of America's diversity, but significant gaps remain. Christianity, particularly Protestant denominations, remains heavily overrepresented compared to the general U.S. population. Meanwhile, women have made steady gains in congressional representation, though they still account for a smaller share than their proportion in the broader public. Similarly, while the number of openly LGBTQ+ lawmakers has risen in recent years, they continue to be underrepresented relative to the American population.

These trends show that while progress has been made toward a more inclusive government, full representation across key identity groups is still a work in progress — and the makeup of Congress continues to shape which perspectives are most heard in national policymaking.
