Fair Maps for California

Using data science to fight gerrymandering and ensure fair representation

Every 10 years, electoral districts are redrawn. When politicians draw these lines to favor themselves, it's called gerrymandering. We use advanced algorithms to create thousands of fair alternatives, ensuring every community has equal representation.

What is Gerrymandering?

The Problem

Gerrymandering is when politicians draw electoral district boundaries to give their party an unfair advantage. It's fundamentally undemocratic, and is essentially rigging elections.

Real Example:

Imagine a city with 60% of voters choosing Party 1 and 40% Party 2. With gerrymandering, politicians could draw districts so that Party 2 win 60% of the seats despite having only 40% of the votes.

Fair vs. Gerrymandered Districts

Comparison

Fair Districts

Compact, logical boundaries

No isolated communities or dilution of voting power

Gerrymandered

Often odd shapess (not compact)

Communities split across several districts

Why Local Redistricting Matters

While national gerrymandering gets headlines, local gerrymandering affects your daily life more directly.

Your Daily Life

Local officials decide on schools, roads, police, zoning, and taxes. These decisions often affect your daily life more than national politics.

Community Voice

When districts are gerrymandered, entire communities lose their voice. Your neighborhood might be split across multiple districts, diluting your influence.

Hidden Impact

While national gerrymandering gets headlines, local gerrymandering often goes unnoticed but has the biggest impact on your quality of life.

Our Data-Driven Solution

Instead of politicians choosing one map, we let computers generate thousands of fair options.

We use advanced algorithms to create 10,000+ possible district maps, and then rank them by fairness. The top 25 plans are presented to the community, ensuring transparency and giving everyone a voice in the process.

Generate 10,000+ Maps

Our algorithms create thousands of possible district configurations using Markov-Chain Monte Carlo (MCMC) methods.

Score for Fairness

Each plan is evaluated using multiple metrics including compactness (reasonable district shapes) and demographic balance. District are always of equal population.
