ABOUT & DATA

Generation Gap measures the distance between the people who hold power in Congress and the people they are supposed to represent — and makes the case for the next generation to close it.

WHAT_THIS_IS

A Civic Data Project

Generation Gap tracks one number for every member of Congress: how much older they are than the people they represent. We pair each senator and representative with U.S. Census data for their state or district, then show the gap — for individual members, for every state delegation, and for the country as a whole. No spin, no scorecard of who is “good” or “bad.” Just the arithmetic of who is in the room where decisions get made.

WHY_IT_MATTERS

Representation Has a Time Horizon

Representation is not only about geography and party. It is also about life experience, time horizon, and who has to live with the consequences of a vote. Congress is significantly older than the country it governs, and that imbalance shapes which problems get treated as urgent and which get filed under “later.”

Housing costs, healthcare, childcare, education, taxes, national debt, foreign policy, national security, energy, and the long-term solvency of the programs today’s workers pay into are long-horizon decisions whose consequences fall unevenly across generations. Age is not destiny, and it is not a disqualification. But it is not irrelevant either. Where you stand in your own life changes what you treat as urgent, tolerable, or non-negotiable.

THE_POINT

Leadership Is Built By Those Who Show Up

Here is what this project is not: a request that older Americans step aside, or a plea for power to be handed down to the next generation. The point is more demanding than that. Younger generations have to organize, build coalitions, raise money, knock on doors, and put their own names on a ballot.

If Millennials and Gen Z are underrepresented in the rooms where decisions get made, the answer is not to wait to be invited. It is to show up. Run for the school board, the city council, the statehouse. Staff a campaign. Register voters. Build the bench. Generational renewal in this country has never been a gift — every generation before this one had to win it, and so will this one.

Older Americans have earned their seat at the table and their voice in the country’s future. So has everyone else. The point is not that the people in power now are wrong because of their age. It is that the next generation cannot afford to sit out the next two decades waiting its turn.

DATA_SOURCES

Where the Numbers Come From

Every figure on this site is built from public-domain government and open-source data. Nothing is fetched at request time — the data is compiled ahead of release and served as static files.

MEMBER_DATA
unitedstates/congress-legislators
Names, parties, chambers, districts, and birthdays for every sitting member. Public domain.
PORTRAITS
unitedstates/images
Official congressional portraits, served via GitHub Pages. Public domain.
POPULATION
U.S. Census Bureau — ACS 5-Year Estimates
2022 American Community Survey age distributions for the nation, every state, and every congressional district. Public domain.
DERIVED_CALCULATIONS

From these sources we compute each member’s age and generation, their first elected year and tenure, the average age of their constituents, and the resulting age gap. Population breakdowns count voting-age residents (18+), and generations follow standard birth-year cutoffs.

LIMITATIONS

What This Data Can and Cannot Say

01

Member data can lag reality. Vacancies, resignations, special elections, and appointments take time to appear. Figures here reflect the last successful data build plus verified member metadata.

02

Census data has a vintage. Population figures use the 2022 ACS 5-Year Estimates. District boundaries and Census releases change over time, and a Census API key is required for future full refreshes — current numbers are built from the last successful run.

03

Age is one dimension of representation, not the whole story. A younger representative is not automatically a better one, and an older one is not automatically out of touch. The gap is a starting point for questions, not a verdict on any individual.
