Charts and maps

The short answer

Trend draws one area’s history, one line per industry or occupation, with the background shaded in three bands: periods from the published record, periods carried forward from monthly survey data, and projected periods. Concentration shows location quotients against the nation for one level of the classification, as a table and bars. Compare sets several areas against one code, as an index from a base year or as levels. The map colours counties in your plan by one measure, with state values for everyone. The table can be downloaded as shown, and every view except the map offers its underlying data as a CSV; the charts themselves are for reading on screen.

The detail

The shading is the same information the disclosure code carries in the table, drawn from the vintage’s provenance boundaries, so a line entering the projected band is a line built by the projection method rather than measured. Hovering a point shows its value, its disclosure and its reliability score, or “N/A” for carried-forward and projected periods, which have none. Reliability is never used to colour a map or a chart. Concentration is computed on employment against the nation and flags a small base where an area has fewer than ten jobs in the code, because a quotient on a handful of jobs is not a finding. The map’s colour ramp has the same five steps on every map; counties outside your plan are neutral, and a state’s unallocated area appears on no map.
