Cuisine turnover methods
Choose Detailed Stats to compare and sort all records in this report.
Cuisine turnover measures concept churn, closure velocity, same-address turnover pressure, and same-address displacement.
License delinquency and ownership changes are separate signals. Neither alone proves that a restaurant has closed.
Evidence taxonomy
| Official record | A direct DBPR or Sunbiz status, inspection, filing, or action. |
| RiskyEats calculation | A deterministic calculation from cited official records, with scope, period, numerator, and denominator. |
| Model forecast | A probabilistic output with an as-of date, model version, uncertainty, and known limitations. |
| Editorial finding | A reviewed interpretation supported by linked evidence and subject to the correction policy. |
Metric dictionary
| Emergency-order recommendation | inspection disposition count | stated report window | An official DBPR inspection outcome; it is not the same as a permanent closure. |
| DBPR 45/46 status | license count or share | as-of date shown | A delinquent or inactive regulatory status, not automatic proof that the storefront closed. |
| Inspection-pattern anomaly | peer-relative analytical band | stated observation window | A record outside its comparison range and a lead for review, not a violation finding. |
| Closure-pressure forecast | calibrated probability | 90-day model horizon | A model estimate, not an official status or guaranteed outcome. |
Closure-pressure model card
| Objective | Prioritize aggregate closure-pressure research and reviewed case leads. |
| Excluded use | Do not treat a forecast as an official closure, food-safety determination, credit decision, or unreviewed accusation. |
| Outcome horizon | 90 days. |
