Residency Intelligence — Public Methodology

This is the public methodology for the generic residency intelligence published by the `[RP] Residency Portfolio` extension. It explains how the public city, jurisdiction, immigration/stay, cost, and fact-check material is sourced and bounded. It is general information only and is **not** legal, tax, immigration, or financial advice. It contains no personal scenario, portfolio, or decision material.

What rotation means

Seasonal residency rotation is the general strategy of spending parts of a year across more than one city or jurisdiction. Whether, where, and how anyone may do so depends on that person's nationality, immigration status, tax facts, and professional advice. This public material describes generic rules and options; it does not select, recommend, or settle a rotation for any individual.

Source model

Public residency intelligence is composed from governed, periodically reviewed records:

• **Cities** — neutral city metadata (country, region, currency, observation
• **Jurisdictions** — generic rule-family summaries (immigration vs tax residence
• **Immigration / stay options** — generic admission, extension, and residence
• **Costs** — static, crowd-sourced cost observations in local currency with the
• **Fact-check** — only explicitly public, generic source claims are published,

**Analytics** use static official population, urbanisation, and country-level GDP per-capita PPP observations with explicit source, year, geographic definition, confidence, coverage, and review metadata. Population shares and historical CAGRs are formula-derived from aligned observations. Unsourced projections remain explicitly unavailable.

Currency and freshness

Cost observations are recorded in local currency with their observation period. Any conversion to a display currency uses a separate live foreign-exchange step with its own provider and as-of date; the underlying cost observation remains static source data.

Place Momentum Signal

Some intelligence-ready cities carry an additional Place Momentum Signal: an interpretive, dated reading of the city's own development trajectory — `rising (strong)`, `rising (mild)`, `matured plateau (vital)`, `matured plateau (stale)`, or `past prime`. It is built from two independent kinds of publicly citable evidence:

• **Bustle evidence** — visible, functioning urban infrastructure: transit
• **Boom evidence** — macro-economic momentum: investment inflow, business or

A reading requires both kinds of evidence, each with its own source, title, and checked date. Neither proxy is treated as sufficient alone: dense, well-connected cities can still be past their prime, and rising cities are not always dense yet. The two proxies are reported side by side precisely so a reader can see where they agree and where they diverge, rather than being collapsed into a single unexplained label.

This is an interpretive reading of independently observable signals, not a score, not a prediction, and not investment, relocation, or financial advice. It carries no personal application, no lived experience claim, and no Architect-specific projection; it describes the place, not any individual's plan. Like every other public observation in this package, it is dated and subject to revision as evidence changes.

Limits

This material can be incomplete, can lag source changes, and can be wrong for a specific person's facts. Confirm anything that matters with a qualified professional in the relevant jurisdiction before relying on it.
