The Institute for Legislative Analysis (ILA) is a 501(c)(3) nonprofit research organization and home of the Limited Government Index. ILA maintains comprehensive congressional and state legislative policy and voting datasets, providing leading liberty-minded organizations with the research, data, and technology needed to advance limited government.

Our Mission

Advancing the limited government principles of the U.S. Constitution by increasing transparency within Congress and the 50 state legislatures.

Our Approach

Constructing comprehensive policy and voting datasets for leading liberty-minded organizations and bringing the movement together through research and technology.

The Problem

Government Has Grown Beyond Its Constitutional Limits

The Constitution established a government accountable to the people, with limited powers and a system of checks and balances designed to restrain government growth and protect individual liberty. Those principles helped create the conditions for unprecedented freedom and prosperity, yet the size, scope, and cost of government have expanded far beyond the limits our Founders envisioned. Rising spending, debt, unfunded liabilities, and an ever-growing regulatory state threaten both our nation’s fiscal stability and the constitutional principles of limited government. Simply put, we do not need this level of government, and we cannot afford it.

The Solution

Restoring Limited Government Through Legislative Accountability

Restoring limited government ultimately depends on the lawmakers elected to represent us, yet understanding how those lawmakers actually vote is no simple task. Thousands of complex bills, amendments, and procedural votes move through Congress and state legislatures each year, making it nearly impossible for the average citizen to evaluate an elected official’s full record. Legislative indexes bridge that gap by translating complex policy into accessible information and providing a transparent measure of where lawmakers stand.

ILA was established to bring that transparency to the liberty movement. Through the Limited Government Index and our legislative database, ILA analyzes policy and voting records across Congress and the 50 state legislatures, evaluating lawmakers against the enduring limited government principles of the U.S. Constitution. Rather than shifting with political personalities or changing priorities, our standard remains the same: the constitutional principles of limited government.

Serving as the “Data Hub”

Equipping the Liberty Movement with Research, Data, and Technology

Advancing limited government requires organizations at the national, state, and local levels to have access to reliable legislative research and data. ILA serves as a data hub for the liberty movement, partnering with organizations across the country and equipping them with the research, technology, and tools needed to advance their individual missions. By providing a shared foundation of comprehensive policy and voting data, ILA helps organizations reduce duplicated efforts, maximize resources, and better hold lawmakers accountable.
ILA’s data supports a wide range of applications, including legislative scorecards, academic research, candidate evaluations, grassroots advocacy, and policy engagement. Rather than dictating how organizations use that information, ILA provides the underlying infrastructure that allows national and local groups alike to turn reliable legislative data into meaningful action.
To put the scale of that work into perspective, the 2026 Limited Government Index alone included:

Our Research Process

Comprehensive Research Behind Every Vote and Rating

Reliable legislative data begins with rigorous research. ILA’s analysts use a multi-step review process to identify, analyze, and verify key bills, amendments, procedural votes, and the voting records of lawmakers across Congress and state legislatures. Our team reviews legislative text, testimony, fiscal notes, journals, and local reporting while consulting policy experts and navigating the unique legislative procedures of each jurisdiction.
This hands-on approach allows ILA to capture important votes and procedural actions that automated and commercial data platforms can miss. Every piece of research is evaluated with the same goal: producing an accurate and representative record of the issues considered by each legislature and providing organizations and the public with legislative data they can trust.
