# Pattern-of-Life Analysis **Entity class:** Analytical method **Domain:** Intelligence / surveillance / investigations **Maturity:** Developed ## Definition **Pattern-of-life analysis** reconstructs recurring activities and deviations across time and place. Inputs may include travel, communication, transactions, device events, locations, encounters, work routines, and relationships. Its purpose is to establish a temporal baseline and identify behavior that warrants further explanation. A credit-card transaction may contribute a time-and-place observation, but merchant, processor, issuer, payment network, and government reporting systems hold different portions of the record. An anomaly is not guilt: ordinary life produces irregularity, shared devices, travel changes, and ambiguous co-location. ## Relationships - **supports:** [[wiki/Counterterrorism Intelligence|Counterterrorism Intelligence]]. - **data layers:** [[wiki/Financial Transaction Data|Financial Transaction Data]], [[wiki/SIGINT|SIGINT]], and [[wiki/OSINT|OSINT]]. - **network counterpart:** [[wiki/Identity and Relationship Analysis|Identity and Relationship Analysis]]. - **temporal representation:** [[wiki/Temporal Network|Temporal Network]]. ## Sources / Provenance - [Treasury — Office of Intelligence and Analysis](https://home.treasury.gov/about/offices/terrorism-and-financial-intelligence/oia) - [[research/Immigration and Customs Enforcement Pattern Analysis and Information Collection (ICEPIC)|ICEPIC research dossier]] ## Connected marketplace roles The source article connects this entry with [[wiki/Behavioral Profile|Behavioral Profile]].
