Market Research Using Government Data: Methodology and Best Practices

Why Government Data Is Superior for Market Research

Market research typically relies on surveys, sampling, and estimation — introducing uncertainty at every step. Government company registration data is different. A company either registered or it did not. This is census data, not sample data — the entire population, not an estimate.

Measuring Market Size

How many companies in sector X operate in country Y? With Companies House data, you can answer it precisely for the UK: filter by SIC codes for sector X, status = active, and count. The result is the actual number of registered limited companies in that sector — not an estimate.

Trend Analysis: Formation Rates Over Time

Monthly company formation data lets you track how a market is growing or shrinking over time. A rising formation rate indicates market confidence and growth. A falling rate can indicate consolidation, regulatory pressure, or economic headwinds.

Citing Government Sources

"Companies House data shows 45,000 active companies in the fintech sector (SIC 64, 66)" is a more defensible citation than "according to an industry report, the fintech sector comprises approximately 40,000–50,000 companies." Stakeholders and investors treat official government data with appropriate authority.
