Data Context

Data context is the layer between a beautiful graphic and a useful reference. A chart can be visually clear and still be misunderstood if the reader misses the unit, denominator, source, time period or caveat.

This page explains how to read USDTWD.ai graphics before citing, sharing or reusing them.

The three-part reading method

1. Read the image. The visual gives the headline comparison and the main values.
2. Read the dataset card. The page lists the key numbers in text so they can be scanned, copied and checked.
3. Read the source and methodology block. This is where the source trail, units, caveats and calculation notes live.

Categories are discovery tools

The library uses nine public categories: FX currency, economy, stock market, demographics, social stats, AI and tech, popular culture, health and government. Categories help discovery; they are not rigid academic claims. A housing affordability graphic may touch economy, demographics and policy, but it should still have one clean primary category.

Units change meaning

Current US dollars are not inflation-adjusted dollars. NT dollars are not US dollars. Monthly wages are not annual income. A ratio is not a percentage. A per-capita figure is not a total. Every serious use should check the unit before repeating the number.

Denominators matter

Rates and ratios depend on the denominator. A percentage of households, a percentage of GDP, a percentage of workers and a percentage of internet users can tell very different stories. The denominator should be visible in the title, subtitle, dataset card or source notes.

Time periods need care

A 2005-versus-2025 comparison is compact and useful, but it compresses two decades of policy, business cycles, currency moves, demographic change and measurement revisions into one before-and-after view. Use these graphics as signposts, not as complete explanations.

Nominal versus real values

Nominal values are stated in the money of the period shown. Real or inflation-adjusted values try to remove the effect of price changes. If a graphic says current dollars, current US dollars or nominal, do not treat it as inflation-adjusted unless the page explicitly says so.

Estimates and latest available data

Some latest-year figures are estimates or latest available values. That is normal in macro and public-stat work, but the page should say so. If the estimate is central to the message, treat it with more caution than a finalized historical value.

Style variants do not change the statistic

A graphic page may include multiple visual styles. The style changes the presentation, not the underlying statistic. Use the clearest style for your audience, and link back to the canonical page so readers can find the source context.

Responsible reuse

For social posts, newsletters and editorial references, the graphic may be enough when attribution and source notes remain visible. For reports, investment research, academic work, policy documents or commercial products, verify the original source and read the Use & Licensing page.
