Volatility is the subject. The meta-trend is faster dashboards and sloppier captions.
KOSTAT, ONS and SSA will keep being the grown-up sources.
Cycles
- Media crown → copy → avoid — A published peak can sow its own decline.
- Decade retro — 20-year and 70-year echoes appear in files.
- Cluster exhaustion — An ending tires and another rises — Lieberson.
- App “live” cycles — Noise on a weekly scale the registrars do not even measure.
- Cross-border leaks — A U.S. chart influences an English parent, and vice versa — still not a world rank.
Signals
- Official release calendars — The only opening bell.
- Methodology notes — Thresholds and sex categories.
- Top-10 share — Concentration vs long tail.
- Unsourced widgets — Negative signal.
Outlook
- More offices publishing — Better comparative work if we keep jurisdictions separate.
- More fake live ranks — Our citation rule gets more important.
- Stable theory — Lieberson still fits the curves better than celebrity myths alone.
The future of name trends is more data and the same obligation: date it or drop it.
