The prompt
In Nigeria, by how much have prices increased in the past 5 years? By how much have salaries increased? How has the percentage of people living below the poverty line changed? What are the main causes of this change?

In Nigeria, prices have experienced a cumulative increase of approximately 180% over the period from 2021 to 2025, based on compounded annual inflation rates that averaged around 23% per year during this timeframe. 3 This calculation accounts for annual inflation figures of 17.0% in 2021, 18.8% in 2022, 24.7% in 2023, 31.4% in 2024, and 23.0% in 2025, reflecting persistent upward pressure on consumer prices.
Average salaries in Nigeria have risen by an estimated 20-30% cumulatively over the same five-year period, with annual increments typically ranging from 7-8% in various sectors, though these figures vary by industry and skill level. 15 Minimum wages saw a more substantial adjustment, increasing by 133% from NGN 30,000 to NGN 70,000 per month in 2024, but overall wage growth has not kept pace with inflation, resulting in reduced real income for many workers. 24
The percentage of people living below the international poverty line of $3.00 per day (in 2021 purchasing power parity terms) has risen from 41.8% in 2021 to a projected 53.3% in 2025, representing an increase of 11.5 percentage points and affecting an additional approximately 30 million individuals amid population growth. 36 Using Nigeria’s national multidimensional poverty index, which incorporates deprivations in health, education, and living standards, the rate stood at around 53.7% in 2017 but has escalated to an estimated 62.9% by 2021, with projections indicating further deterioration to about 61-62% by 2025 due to ongoing economic pressures. 38
The primary causes of this increase in poverty rates include persistent high inflation eroding household purchasing power, naira depreciation leading to elevated import costs, removal of fuel subsidies in 2023 which raised energy and transportation expenses, insecurity disrupting agricultural production and food supply chains, and insufficient wage adjustments relative to price rises. 37 Additional factors encompass structural economic dependencies on oil, environmental degradation from climate events such as floods, and policy implementation challenges like corruption and inadequate targeting of social programs, all of which have compounded vulnerabilities in rural areas where poverty is most acute. 45
Compare to Ghana’s economy
In Ghana, prices have experienced a cumulative increase of approximately 174% over the period from 2021 to 2025, based on compounded annual inflation rates that averaged around 22% per year during this timeframe. 1 This calculation accounts for annual inflation figures of 9.97% in 2021, 31.26% in 2022, 38.11% in 2023, 22.85% in 2024, and an estimated average of 12% in 2025, reflecting a peak in inflationary pressures mid-period followed by a significant decline to single-digit levels by late 2025. 7 Compared to Nigeria’s cumulative price increase of around 180% over the same period, Ghana’s trajectory shows a similar overall magnitude but with greater volatility, including higher peaks in 2022-2023 and a sharper deceleration thereafter, which has contributed to improved price stability by early 2026.
Average salaries in Ghana have risen by an estimated 80-100% cumulatively over the five-year period, driven by substantial public sector base pay increments, including 4% plus a 15% premium in 2021, 15% cost-of-living allowance in 2022, 30% in 2023, and 25% in 2024. 21 Minimum wages also increased steadily, reaching 19.97 Ghanaian cedis per day in 2025 from lower levels earlier in the period. 24 In certain years, such as 2023-2024, wage growth outpaced inflation, leading to real income gains, though this was not consistent across the period. 26 By contrast, Nigeria’s salary increases were more modest at 20-30% cumulatively, with a notable 133% rise in the minimum wage in 2024, but overall adjustments failed to match inflation, resulting in eroded real wages for many.
The percentage of people living in multidimensional poverty in Ghana has decreased from 24.9% in the fourth quarter of 2024 to 21.9% by the third quarter of 2025, representing a decline of 3 percentage points and lifting nearly one million individuals out of poverty within that year. 12 Using the international extreme poverty line of $2.15 per day, approximately 6.9 million Ghanaians were affected in 2024, with trends indicating further improvement into 2025. 15 This downward shift stands in stark opposition to Nigeria, where poverty rates rose from 41.8% to 53.3% under the $3 per day threshold and from around 53.7% to 61-62% multidimensionally, adding millions to the impoverished population.
The primary causes of Ghana’s poverty reduction include targeted fiscal policies under an International Monetary Fund-supported program, such as doubling cash transfer benefits through the Living Empowerment Against Poverty initiative in 2023 and again in 2024, alongside subsidies that shielded vulnerable groups from economic shocks. 30 Broader economic recovery was facilitated by debt restructuring, reduced fiscal deficits, and improved macroeconomic stability following the impacts of the COVID-19 pandemic, Russia’s invasion of Ukraine, and prior excessive government borrowing. 31 These factors contrast with Nigeria’s challenges, where poverty escalation stemmed from persistent inflation, currency depreciation, fuel subsidy removal, agricultural disruptions due to insecurity, and inadequate wage adjustments relative to price surges, compounded by oil dependency and governance issues.
