Confidence and sources

Data are current through 11 September 2026. Every node was compiled from at least one reference, official, plan or press source and the 371 nodes cite 401 register entries: 126 press, 121 reference, 109 official, 30 database, 15 plan. A fact check pass verified the year, status wording and every dated or numeric claim of the seventy four most connected nodes and the case nodes against their cited sources, and its corrections are in the dataset; the sub claims it could not confirm are listed below. Each node carries a confidence grade in the index and in the interactive map: High means an official site, a public plan, a Census table or two press reports; Medium means Wikipedia or a single press report; Low means a year or detail the sources leave unconfirmed. Of the 371 nodes, 206 are High, 159 Medium and 6 Low. The preferred evidence for each kind of claim is set out below; where a claim rests on a weaker tier than its preferred one, the wording says reported.

Source hierarchy

Core chronology rests first on municipal archives, National Register records, county archives, state historical resources, the National Park Service, FDOT, Miami-Dade County, the Census and institutional histories. Wikipedia is a secondary locator and reference source, not the only support for core dates, incorporation claims, storm impacts, major infrastructure or landmark origins. Nodes that are central to a case, a top twenty metric, the towns layer or an Andrew flagged asset and that currently rest on reference sources alone are flagged for source upgrading in the Nodes sheet (23 nodes); none is removed for that reason.

Status taxonomy

Every node carries three fields. Entity status is operating, open, active, closed, dissolved, delivered, under construction, approved, proposed, announced or historical, as the sources word it; events, deceased people and defunct institutions are historical, never active. Historical state is pre Andrew, Andrew affected, rebuilt or replaced, post Andrew or not applicable, set from the year the node enters and the Andrew flag. The Andrew flag marks the storm itself and every node a source records as destroyed or heavily damaged in August 1992 and rebuilt or replaced.

Terminology and names

ZCTA means a Census ZIP Code Tabulation Area; the population series is a ZCTA series, not a USPS ZIP Code series. South Dade means the frame drawn on the Cities view: the four municipalities and the census designated places south of about SW 136th Street. Community hub means the municipality or census designated place a node sits in by address or centroid. The Transitway is the county's name for the corridor that opened as the South Miami-Dade Busway; the map uses both as the sources do. Developer means any firm or fund with a documented role on a named project, including lenders and land sellers where the source names them. Gathering place is the map's own flag for a documented place where people gather: a market, a theatre, a park, a main street, a festival, a church, a civic hall, a restaurant of standing. Compound descriptors are written without hyphens throughout as a house convention.
