demotools
The toolbox that became a workshop
demotools sounds like a tidy little utility drawer, but its sustained updates and broad demographic flavor suggest the drawer has quietly expanded into an entire workshop.

Roasts
demodecomp
Decomposition season
demodecomp takes the bold stance that one demographic answer is never enough, then keeps splitting the question until the spreadsheet starts asking for its own decomposition.
decomp_sullivan
The Sullivan special
decomp_sullivan has the wonderfully specific energy of a repository created after one method refused to leave the research agenda alone.
hmdhfdplus
Mortality, but make it modular
hmdhfdplus sounds like the sequel where mortality data returns with bonus health and frailty content, proving even grim statistics can get an expansion pack.
ddsqltools
SQL enters the demography lab
ddsqltools is the crossover episode: demographic analysis meets SQL, presumably so the data can be queried before it gets decomposed again.
Category breakdown
Impact
25% weight
The projects form a coherent, specialized body of demographic, mortality, decomposition, inequality, and coverage work, suggesting substantial practical and research value.
Consistency
15% weight
The visible portfolio shows sustained activity across many years, with numerous repositories updated in 2025-2026 and several active, non-fork projects.
Quality
25% weight
Repository names, non-fork ownership, active status, and repeated domain-specific tooling signal mature project intent, though implementation quality cannot be assessed from metadata alone.
Depth
20% weight
The long-running profile, specialized tool repositories, and continued work across related analytical projects indicate sustained ownership and meaningful domain depth.
Breadth
10% weight
The supplied repositories are overwhelmingly R-based and concentrated in demography and population analysis, giving strong thematic variety but limited language and project-type variety.
Community
5% weight
Follower and star counts provide a modest positive signal, especially for demotools, but community evidence is limited and does not materially drive the other scores.

Impact · 82/100
What it measures. Project usefulness, ambition, originality, and coherence. Popularity is not impact.
Evidence for timriffe. The projects form a coherent, specialized body of demographic, mortality, decomposition, inequality, and coverage work, suggesting substantial practical and research value.
Quality · 70/100
What it measures. Engineering and project-maturity signals supported by the available public metadata.
Evidence for timriffe. Repository names, non-fork ownership, active status, and repeated domain-specific tooling signal mature project intent, though implementation quality cannot be assessed from metadata alone.
Depth · 86/100
What it measures. Sustained ownership, meaningful scope, and continued maintenance rather than one-shots.
Evidence for timriffe. The long-running profile, specialized tool repositories, and continued work across related analytical projects indicate sustained ownership and meaningful domain depth.
Consistency · 88/100
What it measures. Recency and contribution patterns across the supplied activity window.
Evidence for timriffe. The visible portfolio shows sustained activity across many years, with numerous repositories updated in 2025-2026 and several active, non-fork projects.
Breadth · 43/100

Evidence for timriffe. The supplied repositories are overwhelmingly R-based and concentrated in demography and population analysis, giving strong thematic variety but limited language and project-type variety.
Community · 57/100
What it measures. A weak positive tie-breaker for supplied community signals, never a popularity penalty.
Evidence for timriffe. Follower and star counts provide a modest positive signal, especially for demotools, but community evidence is limited and does not materially drive the other scores.

I. How this saved profile rating was produced
- 01
Validate. The server validates the login, signed browser session, attempts, cooldown, daily ceiling, and the single provider permit.
- 02
Collect. The VPS collector reads bounded public profile metadata and up to 12 recent repository metadata rows in volatile memory.
- 03
Rate. One pinned provider returned a closed profile-rating object with no tools, browsing, shell, or repository-content access.
- 04
Verify. Server checks bound the subject, rejected unsafe or echoed text, validated the schema, and recomputed rubric-v3 final arithmetic.
- 05
Save. Only a valid completion and allowlisted post-completion facts commit atomically; the public projection is then rebuilt.
This saved profile analysis is metadata-only and did not read repository trees, README files, or source code. Availability of new analysis is separate from this historical result.

II. Data sources & caveats
- Scores summarize one accepted, subject-bound analysis; they are not a security audit or endorsement.
- Rank, percentile, and median use 1095 currently accepted public profiles and can change as the leaderboard changes.
- Repository and language details reflect the bounded analyzed sample, not necessarily every repository.
- Missing data is shown as unavailable or not evaluated instead of being inferred as zero.
- Analysis completed Aug 10, 2026, 1:58 AM UTC and is marked aging.
