Sectors

The award records for Tanzania have no CPV code, so this story has no sector table.

CPV sector: the sector of the award's CPV code, the EU classification of what a contract buys. Our keyword sector labels elsewhere on the site can give other counts.

How we counted

  • TANePS award notices for Tanzania. One record is one contract award: a buyer, a supplier, a date and, where the source gives it, an amount.
  • September 2024 to March 2026. We hold 19 months of data for Tanzania, so the window has 19 months, not 24.
  • The records for Tanzania have no CPV code, so this story shows no sector numbers. We do not use our keyword sector labels: a hand check found too many wrong labels for most sectors.
  • We count each award once: one notice, one amount, one date. We leave out awards with no supplier name, placeholder names such as "persona natural", names that are only a legal form, and names that appear on thousands of unrelated awards.
  • We count suppliers by normalised name. A firm under two spellings counts as two suppliers, so the "won one award" share is an upper bound.
  • Stated value is the amount in the award notice, in TZS. It is often the ceiling of a framework agreement, and the money paid can be lower. When several winners share one notice and one amount, we split the amount. We cap each award at the 99.9th percentile of the awards in Tanzania. 100% of the awards state an amount, TZS 457 billion in total.
  • These numbers show how the awards spread across suppliers. They do not show why.

The method is the method of our study of 39 countries: who wins government contracts. Other countries: who wins, country by country. The sector pages show the same numbers for each country and sector with enough data.
