Country Ghosts Dashboard

Country-linked ghost watchlists surface a different geography of deep CT.gov silence

France leads on excess ghost stock, China and Egypt remain close behind, South Korea adds a strong black-box component, and several other mid-sized portfolios remain sharper than their raw size alone would suggest.

France leads on ghost excess, China and Egypt stay close, and South Korea stands out as a high-black-box geography as well as a ghost outlier.

France leads, but the next cluster is driven by China, Egypt, and South Korea.
This is the geography of deeper silence rather than ordinary missing-results stock.

Raw ghost counts still keep France and China near the top, but they also show the scale of the broader European portfolios.
The stock table and excess table need to be read together.

France and China also carry large black-box stock, while South Korea is especially notable on black-box rate.
That gives the country-ghost table a deeper-silence overlay.
