# Expose Respondent Mix Before Applying Supplied Population Weights — Free

A heavily responding small district can dominate the raw percentage. Compare the respondent mix with a supplied population frame, while keeping the strong assumptions behind any reweighted estimate in plain view.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

Community organizers describing survey limitations honestly

## What's free

- one complete unwatermarked response-mix chart run in the app
- three labeled samples and unlimited article-demo calculations
- complete result text and a user-triggered input-state link

## Optional paid add-on

**$4 one-time.**

- unlimited subsequent response-mix chart app calculations after a local convenience signal
- print the response-mix chart with visible assumptions and its safety boundary
- CSV of the displayed % population-weighted affirmative and row workings; conditional estimate uses your manual-retyping minutes
- five local reading summaries (headline/count/time), not saved full inputs or cross-device backups
