Data Analysis: Fewer than 1 in 12 Nigerian politicians have English Wikipedia biographies

Of an estimated 24,780 distinct Nigerian legislators and political appointees since 1923, only 2,066 have entries on English Wikipedia. On an article-count basis, that is about 8.3% coverage. Coverage is concentrated at the federal level; state-level offices are sparsely documented.

Scope of this analysis

This report examines the presence of Nigerian public office-holders on English Wikipedia across the following categories: Legislative Council (elected and appointed, 1923–1947), House of Representatives (1954–1964 and 1979–2019), Senators (1979–2019), State Houses of Assembly members, Governors, Deputy Governors, Federal Ministers, State Commissioners, Presidents and Vice Presidents.

Coverage by category

* Governor and Vice-President counts exceed 100% because the supplied coverage numbers reflect Wikipedia entries rather than deduplicated individuals; multiple listings, repeat office terms and category overlaps inflate the article count.
** The overall “uncovered” figure is a lower bound. Because coverage totals are inflated by cross-category duplication, the true number of missing biographies is at least 22,714.

Key observations

• State-level offices are the least documented. Only 2.6% of State House of Assembly members and 1.0% of State Commissioners are covered. In absolute terms, these two categories account for the largest gaps: an estimated 10,066 missing Assembly biographies and 7,983 missing Commissioner biographies.
• Federal legislature coverage is low. Only 6.7% of Senators (1979–2019) and 11.8% of post-1979 House members have pages. Pre-1966 House coverage is comparatively higher at 52.4%, reflecting concentration of historical documentation.
• Top offices are mostly present but not complete. Presidents are at 87.5% coverage and Federal Ministers at 34.8%. Deputy Governors stand at 27.1%.

Methodology

• Totals. Category totals reflect the number of seats/office-holders across the specified periods:
  • Legislative Council elected seats (1923–1947): 24; appointed seats: 46.
  • House of Representatives: 1954 (184), 1959 (312), 1964 (312) → 808 total; 1979 (449), 1983 (450), 1992 (593), 1998 (282), and 1999–2019 cycles at 360 each → 3,574 total.
  • Senate: 1979 (95), 1983 (96 incl. 1 vacancy counted as 96), 1992 (91), 1998 (80), 1999–2019 cycles at 109 each → 907 total.
  • State Houses of Assembly: estimated 10,330 distinct members since inception (supplied figure).
  • Governors and Deputy Governors: 214 each (across 1979–2019 cycles).
  • Federal Ministers across administrations (Balewa–Tinubu): 583; State Commissioners: 8,064 possible distinct appointees if no repeats (upper-bound supplied figure).
  • Presidents: 8; Vice Presidents: 8.
• Coverage counts. “Currently covered” reflects supplied counts of English Wikipedia entries per category. The House of Representatives coverage figure (423) includes “404 HoR members + 19 women” as provided. The women’s counts for HoR (19) and Senate (12) are included within the 423 and 61 tallies respectively.
• Computation. Percentages are covered ÷ total. “Uncovered” is total − covered where coverage ≤ total. Where coverage > total (Governors, Vice Presidents), “Uncovered” is not reported; these categories indicate article-level inflation and duplication.
• Overall figures. The overall coverage rate (8.3%) is computed on an article-count basis by summing totals and summed coverage. Because the coverage sum includes cross-category duplication (e.g., an individual may be both a Senator and a Governor), the “covered” total is inflated. Therefore, the estimated “uncovered” figure of 22,714 is a conservative lower bound.

Limitations and interpretation notes

• Deduplication not performed. Individuals holding multiple offices across time or categories are counted multiple times in coverage totals. Figures should be interpreted as article counts, not unique persons, unless otherwise stated.
• Commissioners total is an upper bound. The 8,064 total assumes no repeat appointments; actual distinct individuals are likely fewer. This means the 1.0% coverage rate for commissioners is conservative (true rate may be slightly higher), but the absolute gap remains large.
• Period splits for the House of Representatives. The same coverage figure (423) is applied to both 1954–1964 and 1979–2019 series due to how the source data were supplied. By-era coverage should be treated as indicative.
• Quality not assessed. Presence of a Wikipedia article does not imply completeness, neutrality or sourcing quality. This analysis is about the existence of entries.
