Job-change data glossary

The terms used across Live Data Technologies guides and research, with a short definition for each.

Records and events

Job change: A dated event in a person's working life: they joined a company, changed title or left.
Person record: One person and the dated events of their working life. Each record lists their jobs, with employer, title, function and dates.
Arrival: A person joining a company, recorded with the date it was first observed.
Departure: A person leaving a company. A departure comes with the next employer when there is one.
Destination: Where a person went next after leaving a company.
Title change: A new title at the same company, recorded as its own dated event next to joins and exits.
Stale contact: A contact who has moved since the list was made. People change jobs, and an older list holds more people who have since moved.

Re-verification: Checking a person's record again after it was first collected, so a move shows up as a new dated event. At Live Data, every profile is re-verified on a 10 to 14 day cycle.
Continuous re-verification: Live Data's method of re-checking records on a continuous basis across the whole database.
Refreshed: A word data vendors use in three ways: a timer refresh, a triggered update or whole-record re-verification. Each catches different changes.

Parent company roll-up: Counting people across a whole parent company, because company records link to their parent.
Company-level metrics: Measures of a company built from its people: workforce movement, employee tenure and retention.

Two-year exit rate: The share of people who started a role in a given year and had left it within two years.
Start-year group: Everyone who started a role in the same year. Comparing groups shows how exits differ by start year.

Job change alert: A notice of a change for the people or companies you track, sent by webhook or in a daily batch file.
MCP server: The way to use Live Data from an AI assistant such as Claude or Cursor, at mcp.gotlivedata.com.
Data test: Send a list and Live Data shows which records are stale and what changed.
Workforce intelligence platform: A tool that shows who works where and how that changes over time: who joins a company, who leaves and where people go next.
Kinds of workforce data: Job postings show what a company plans to hire. Headcount shows how many people it has. Job histories show what each person actually did.
