When numbers have time

Debt is an abstraction. A line in a press release, a cell in a budget report, a blank in the Bank of Korea’s ECOS — it rests there until the next release. This site gives time back to those frozen numbers: it takes the most recent official snapshot as the starting point and interpolates each instant using the published annual growth rates.

The method

Every card is computed with a simple compound interpolation: value(t) = base × (1 + g)^((t − t₀) / 1y). Both base and g come from the official statistics as of the base date shown at the top of the page. This is not measurement but estimation, always refreshed at the next release.

Why show it

Debt becomes political only when its speed is visible. A counter ticking by the second makes the increment — not the absolute — legible. “2,500 trillion won” is abstract; “12 million won every second” is concrete. We hope that concreteness nudges the civic sense of macro.

Limitations

These are interpolated estimates. Policy, FX, or rate shocks will pull actual statistics off this trend. Source links appear on every card — for decisions, always check the primary data.

Data limits and reliability

The live figures on screen are estimates interpolated between two official releases, and the next confirmed print can revise them after the fact. Not every series carries the same weight either, so each one is tagged by confidence — official (confirmed), estimate (interpolated), or proxy (a stand-in indicator). For anything that matters, follow the source under each card and read the primary data yourself.

How to use and cite

When you quote a figure in an article or paper, use the snapshot API (/api/korea/snapshot.json), which pins a single instant. Copy the baseAsOf and citeAs fields from the response and your reference becomes reproducible. To put the numbers on your own page, build an embed in the widget studio (/widget/studio) or call the public JSON API directly. Treat this site as a companion that adds a sense of time to otherwise frozen official statistics — never a replacement for them.

The principles behind this site

First, every number carries its source and its definition. Debt statistics shift substantially with the definition used, so a figure presented without a source is not information but an assertion. Second, estimates and measurements are labelled apart. The live values on screen are interpolated between official releases, and that fact is not hidden. Third, debts of different natures are never added together. National and household debt have different debtors and different means of repayment, so combining them into one total produces a quantity that cannot be interpreted.

What this site does not do

It does not give investment advice. Debt indicators are not a signal for the direction of asset prices or interest rates, and no screen here is designed to support a buy or sell decision. Nor does it forecast. Interpolation is arithmetic that fills the gap between official releases, not a projection of what the next release will say. It does not advocate for a particular policy or party either. Where interpretations of the same number diverge, the divergence itself is what gets recorded.

Errors and corrections

Official statistics sometimes revise past values as provisional figures become final, and when they do the starting point of the interpolation changes with them. If you find a value here that conflicts with the original source, please tell us through the contact route (/contact/). Confirmed errors are logged on the corrections page (/corrections/) rather than quietly fixed. The formulas, base dates and known limitations are published in full on the methodology page (/methodology/).

Operation and funding

Running costs are covered by advertising revenue. Advertisers have no part in deciding which indicators appear or how they are described, and nothing is adjusted to make a particular country or metric look favourable. All data comes from published official statistics with sources stated, so readers can verify for themselves whether the writing matches the underlying material. The editorial standards are set out on the editorial policy page (/editorial-policy/).
