How the data
gets here.
Every number on this dashboard traces back to an official statistical agency or international organization. This page explains how data flows from source to screen — and what happens along the way.
Ingest
Scheduled workers query each source API for new observations. Every fetch is logged with timestamp and response metadata.
Validate
Incoming data is checked for schema conformance, plausible ranges, and duplicate detection before storage.
Version
Each observation is stored with a vintage identifier. Revisions create new vintages rather than overwriting, ensuring full reproducibility.
Serve
The API normalizes units, applies display scaling, and delivers observations with full source attribution to the frontend.
OECD
SDMX v4Cross-country comparable indicators via SDMX REST API. The primary source for harmonized data that enables direct Canada–US comparisons.
Statistics Canada
RESTOfficial Canadian statistics via Web Data Service. Provides granular domestic data unavailable through international aggregators.
Bank of Canada
ValetMonetary policy decisions, interest rates, and financial market data through the Valet API.
FRED
RESTFederal Reserve Economic Data for US series and select international comparisons.
World Bank
RESTGlobal development indicators and long-run structural data for emerging and advanced economies.
BIS
SDMXBank for International Settlements credit statistics, property prices, and financial stability metrics.
IMF WEO
ForecastOfficial projections from the World Economic Outlook, updated semi-annually.
Vintage Tracking
Every observation is stored with a vintage identifier. When a source agency revises a data point — as routinely happens with GDP, employment, and other headline series — a new vintage is created rather than overwriting the existing value.
This preserves the full revision history and ensures complete reproducibility. If you looked at this dashboard on a specific date, you can reconstruct exactly what was shown, even after the underlying data has been revised.
Projection Methodology
Projection data comes exclusively from official sources — primarily the IMF World Economic Outlook, updated semi-annually. These are the same forecasts used by finance ministries and central banks worldwide.
When projections are displayed on indicator pages, the "implied daily path" is a simple linear interpolation from the last known actual observation to the projected target. This visual aid helps show the trajectory but should not be confused with real data or independent forecasts.
This page describes the methodology as of the current implementation. Data pipelines and source configurations may evolve over time. For questions about specific indicators, see their individual detail pages.
