Cross-indicator analysis, correlation and trend — computed in pure JavaScript · 2020–2026

Ask the Data AI

Ask a plain-language question about Nigeria's economy. The assistant answers only from real figures it retrieves from the platform, and cites the indicator and date for every number. It will tell you when the data can't answer — it never invents figures.

Answers are generated from live figures; correlation is not causation. Not financial advice.
Analyze Any Indicator

Pick any of the platform's 122 indicators — every headline series, all 47 GDP sub-sectors, every currency and CBN balance-sheet item — to see its full analytical profile computed live: latest value, change, year-on-year, range, volatility, trend and a Holt-Winters forecast with a 95% confidence band.

Lead / Lag Explorer

Does one indicator move before another? Pick two series and the tool correlates them at every monthly shift, finding the lag with the strongest relationship. A positive lag means the first series (X) leads the second (Y). This is association, not proof of causation.

Pick two indicators and click Analyze.
Correlation of X with Y shifted by each lag; the gold bar is the strongest. Computed in-browser.
Seasonal Decomposition

Split a series into its trend, a repeating seasonal pattern, and the residual left over. The seasonal-strength score (0–1) says how much of the movement is a regular calendar pattern. Needs at least two full cycles of monthly or quarterly data.

Inflation Trend with Linear Regression

The dashed line is an ordinary least squares (OLS) regression. It slopes upward across the whole window — but a single straight line can't capture the real shape: inflation climbed to a 34.8% peak in December 2024, then eased to 15.4% by early 2026. Read the line as a rough long-run summary, not the month-to-month path.

Pearson Correlation: Inflation vs Exchange Rate

Computing correlation…

Pearson r calculated on paired monthly observations within the selected date range. NBS inflation vs CBN NGN/USD.
FX Reserves and the Exchange Rate — a weaker link than assumed

It's often assumed reserves and the exchange rate move inversely. Over 2020–2026 the data disagrees: as the Naira weakened, reserves dipped to a $32.5B low (April 2024) then recovered, so both actually trend upward. Both series are standardised (z-scores) to share one honest axis rather than a misleading dual axis.

Real GDP by Sector — largest to smallest

The size of each part of Nigeria's real economy in the latest common year, sorted largest first. Every sector is shown for the same year so the bars are directly comparable; sectors without a figure for that year are omitted.

Correlation Matrix — 12 Headline Indicators

Every pair of the platform's core macro series and GDP sectors, correlated on annual averages so monthly/daily series (inflation, exchange rate, reserves) line up fairly against annual GDP sectors. Green = positive, red = negative, brighter = stronger. Grey means too few overlapping years to compute a reliable r. Hover any cell for the exact value.
