Calculates derived metrics (percentage changes, per-capita rates, ratios) from raw numbers and provides plain-language explanations. Useful for journalists or analysts who need defensible, audience-ready figures.

Takes raw numbers you provide and calculates derived figures — percentage changes, per-capita rates, index values, or ratios — with plain-language explanations ready to drop into a story.
Takes raw numbers you provide and calculates derived figures — percentage changes, per-capita rates, index values, or ratios — with plain-language explanations ready to drop into a story.
Required: The raw numbers you want to work with, clearly labelled (e.g. "hospital beds 2019: 42,000 / 2023: 38,500 / population: 5.2 million") Optional: The unit of analysis you want the rate expressed in (per 1,000, per 100,000, etc.); the geographic or time scope; the type of derived metric you want (percentage change, per-capita rate, share of total, index); any known data caveats you want flagged
Short structured response: labelled calculation block showing the arithmetic; one or two plain-language sentences for direct use in copy; a brief caveats note (2–4 bullet points). Total length: under 300 words. Tone is clear and precise — written for a journalist, readable by any audience.
Reported road fatalities in a mid-sized country: 3,840 in 2019 and 2,970 in 2023. Population in 2023: 8.6 million. I need the percentage change between the two years, and the 2023 fatality rate per 100,000 people.
Percentage change, 2019 to 2023
Formula: ((2,970 − 3,840) ÷ 3,840) × 100 = (−870 ÷ 3,840) × 100 = −22.7%
Ready-to-use sentence:
Road deaths fell by 22.7 percent between 2019 and 2023, from 3,840 fatalities to 2,970.
2023 fatality rate per 100,000 people
Formula: (2,970 ÷ 8,600,000) × 100,000 = 34.5 per 100,000
Ready-to-use sentence:
In 2023, the country recorded 34.5 road deaths per 100,000 people — a figure that allows direct comparison with international safety benchmarks.
