The vocabulary of market research.

The published uncertainty around a forecast point. Meridian reports a low/median/high triple rather than a single number when the underlying evidence supports a range. Bands narrow as evidence paths converge.

A figure carried directly from a regulatory filing or sovereign statistical authority. Anchored figures are the strongest evidence class and are not adjusted away in triangulation.

The opening section of every Meridian report that names what is in scope, what is out, and what is deliberately deferred. The boundary is the most honest part of any market estimate.

The constant year-on-year growth rate that reconciles a starting value to an ending value. CAGR smooths volatility and is reported alongside the year-by-year forecast, never instead of it.

Adversarial sign-off by reviewers independent of the authoring analyst. No figure publishes without a committee minute and a red-team memo.

The combined share of the top five (CR5) or top ten (CR10) operators in a sector. A high CR5 implies pricing power; a low CR5 implies fragmented competition.

See top five tables

A per-figure tag, anchored, derived, estimated, that indicates how directly a number rests on a primary source. Every numerical claim in a Meridian report carries a confidence label.

Meridian's path-weighted estimate after triangulation across at least three independent evidence paths. Where evidence paths disagree, the divergence is disclosed alongside the consensus number, never averaged silently.

The public process for fixing material errors in published figures. Corrections are made in place with a dated note; the prior figure is preserved in the revision log.

Breaking a market into the dimensions that drive purchasing, product, channel, indication, geography. Each dimension carries its own share, growth, and confidence label.

A figure produced by calculation from anchored inputs (e.g. an industry total computed from per-firm filings). Derived figures inherit the confidence of their weakest anchor.

The table that records where Meridian's figure disagrees with a published syndicated benchmark. Divergence is disclosed inline, never reconciled to the median.

A figure with no anchored or derived path, typically applied to nascent or thinly-disclosed markets. Estimates carry the widest confidence band and are flagged on the page.

One of five canonical source families ranked by weight: regulatory filings, official statistics, industry benchmarks, syndicated benchmarks, and analyst-conducted primary research.

An independent reasoning chain from evidence to a published figure. A Meridian headline number is reconstructed from at least three evidence paths.

The number of years a forecast extends. Meridian publishes through 2036 by default; commissioned reports extend further on request.

The largest market opportunity if all addressable demand were captured today. TAM is the bound of the market, not a target.

A change to a published figure, ranking, or directional thesis. Material corrections are recorded permanently in the public errata log.

A consensus figure computed by weighting each evidence path by its source class and methodological strength. Stronger paths carry more weight; the weighting is disclosed.

The free, indexed digest of a Meridian report at /markets/{slug}, top-line size, top five companies, region split, sources index. Subscribers see the full report behind sign-in.

Analyst-conducted conversations with operators, buyers, and regulators. The only evidence class that captures qualitative context behind the numbers.

A written critique of the report by a reviewer outside the authoring team. The red-team memo ships alongside the report, not edited out.

How often a published report is reviewed and re-issued. Preview pages refresh every 90 days by default; material events trigger earlier refreshes.

The portion of TAM that an operator can plausibly serve given regulatory, geographic, and product-fit constraints. Always smaller than TAM.

A named forecast variant with its own assumption set, base, accelerated, constrained. Scenarios are not probability-weighted; they describe coherent futures the analyst considers plausible.

The classic technology-adoption shape, slow uptake, rapid acceleration, asymptotic saturation. Meridian fits S-curves to penetration-driven markets where saturation is in scope.

A subset of a market defined by a single dimension (e.g. by indication, by channel). A market may be decomposed into multiple segment dimensions in parallel.

The realistic share of SAM an operator can capture in a defined planning window. The most useful number for go-to-market sizing.

The ranked weighting of evidence classes when paths disagree: regulatory filings > official statistics > industry benchmarks > syndicated benchmarks > primary research. Disclosed on the methodology page.

A third-party service that processes customer data on Meridian's behalf, Clerk, PayPal, Vercel, Neon. The current list is published in the privacy policy.

Reconstructing a figure from at least three independent evidence paths and reconciling the result. Triangulation is the core safeguard against single-source error.

A specific dated version of a report. Every refresh produces a new vintage; prior vintages remain accessible through the revision ledger.

The licensee identifier embedded in every exported PDF, PowerPoint, and Excel file. Watermarks tie a leaked file to the original purchaser.
