You do not need technical words to get started. Describe what is difficult and what you want to make easier. You can send a short inquiry without an account.

  1. Browse services and prices, or go straight to tell me what you need.
  2. Examples are independent public-source demonstrations of spreadsheets, procedures and research comparisons, not paid client work. You can read them without downloading anything.
  3. Use Client Login for private requests, files and project review. Start with the no-account inquiry form; no files are needed.

Have a complex or technical project? Describe it here. The listed packages are starting points. Larger spreadsheets are welcome; feasibility, size and complexity are reviewed before agreeing a custom scope and price.

What changed

From published guidance to a usable handoff.

Before · original source material

Coverage thresholds, periods, table availability and vintage rules live on different Census Bureau pages.

After · finished deliverable

A five-page brief and 50-cell comparison bring five product families onto the same basis, then apply the rules to five concrete research tasks.

The source material is real. Structure, synthesis and decision guidance are Cleargrain’s work. No source defects or business outcomes are invented.

The answer depends on the question

Neighborhood household income calls for ACS 5-year detail. Annual county population growth calls for one Population Estimates Program vintage. The brief explains the source-backed selection rules instead of declaring a universal winner.

A detail a quick comparison could miss

The Census Bureau says separate population-estimate vintages should not be combined. Its current download page also states that current estimates are not supported by the API. Both constraints are preserved in the comparison.

Evidence you can inspect

The workbook compares time period, coverage, purpose, detail, uncertainty, cadence, comparability, access, limitations and sources. The brief links official table definitions and describes five practical research decisions.
