Companies: CRO open data, by the NACE code each company declares. Sector economy: see sources above.
CRO records an activity code (NACE) for 64.0% of active companies (99.2% of those under 5 years old, 99.5% of those 5 to 10 years old, 12.0% of those over 10 years old), so company counts by sector cover the coded companies, which skew young.
