--industry takes a KSIC code by prefix: 26 is the division, 26299 one class. --has takes pension_series, crno, contact or listed. An unknown value is an error naming what is accepted — a typo never looks like "no such companies".

What the numbers are

| | | |---|---| | Employment Insurance | Enrolled workers from the workplace master. Annual. | | National Pension | Monthly subscribers. Excludes those aged 60 and over and includes registered directors, so it differs from the insurance figure by design. |

Every value is a government record as of the date shown — not an estimate, and not an assessment of any company. What is in the data →

Cost

100 credits per company, 100 per search row, 100 for a count, 1,000 for an employment series. Pricing →
