Why polling matters in Nigeria
Nigeria is Africa's most populous democracy, with over 220 million citizens spread across 36 states, 6 geopolitical zones, and more than 500 distinct ethnic groups. Capturing the pulse of this vast, diverse nation requires rigorous methodology, cultural sensitivity, and transparent reporting. Survey Nigeria exists to fill that gap — providing independent, data-driven snapshots of what Nigerians actually think on the issues that shape their lives.
Sampling methodology
A poll is only as good as the sample it draws from. We use a stratified random sampling approach that ensures representation across Nigeria's six geopolitical zones: North West, North East, North Central, South West, South East, and South South.
Data weighting
Raw responses rarely match the true population profile perfectly. Weighting corrects for known imbalances without discarding data.
Post-stratification weighting
After data collection closes, we apply post-stratification weights based on the 2023 NBS population estimates. Respondents from under-represented groups receive a weight greater than 1.0; over-represented groups receive a weight less than 1.0.
Effective sample size
Weighting reduces the effective sample size (ESS). We report both the raw n and the ESS so readers can assess the true precision of each poll. A heavily weighted poll with raw n=600 may have an ESS closer to 420.
Transparency principle
We publish the unweighted topline alongside the weighted result for every poll. If the two diverge significantly, we flag this in the methodology note attached to each result.
Regional breakdowns
Nigeria's six geopolitical zones often hold sharply different views on the same question. A national headline figure can mask profound regional variation — which is why we break every major poll down by zone.
North West
Kano, Kaduna, Katsina, Sokoto, Zamfara, Kebbi, Jigawa
Nigeria's most populous zone; strong APC base; issues of banditry and agricultural livelihoods dominate.
North East
Borno, Yobe, Adamawa, Gombe, Bauchi, Taraba
Heavily affected by the Boko Haram insurgency; security and humanitarian concerns rank highest in surveys.
North Central
Kogi, Benue, Nasarawa, Plateau, Niger, Kwara, FCT
The Middle Belt; farmer-herder conflict is a defining issue; politically competitive zone.
South West
Lagos, Ogun, Oyo, Osun, Ondo, Ekiti
Nigeria's commercial heartland; highest internet penetration; strong LP and APC presence.
South East
Anambra, Imo, Enugu, Ebonyi, Abia
Predominantly Igbo; LP stronghold; issues of marginalisation and security (IPOB) are salient.
South South
Rivers, Delta, Bayelsa, Cross River, Akwa Ibom, Edo
Niger Delta; oil-producing region; PDP historically dominant; environmental concerns prominent.

Interpreting poll results
Numbers without context mislead. Here is how to read Survey Nigeria data correctly.
Polling trends in Nigeria
Nigerian polling has evolved significantly since the return to democracy in 1999. Understanding this history helps contextualise current data.
Polling was sparse and largely conducted by international organisations. Domestic capacity was limited and public trust in data was low following decades of military rule.
NOI Polls, Gallup Nigeria, and a handful of university research centres began producing regular surveys. The 2011 elections — widely regarded as Nigeria's most credible to date — generated significant polling activity.
The APC's defeat of the PDP in 2015 proved Nigerian elections were genuinely competitive. Polling demand surged; several new firms entered the market. Pre-election polls showed mixed accuracy.
Mobile internet growth and the rise of social media have enabled faster, cheaper data collection. Online panels now supplement traditional phone and face-to-face surveys. Survey Nigeria was founded in this era to provide independent, transparent polling.
Data limitations and caveats
Honest polling requires honest disclosure of what the data cannot tell you.
