	census		20
	energy		 3
	environment	19
	geography	11
	health		33
	socioeconomic	24

There are also (concidentally) 110 geographic levels in SEEDIS, including:

	nation and large interstate levels	11
	small interstate levels			20
	state parts of interstate levels	21
	state and large intrastate levels	19
	county levels				16
	place and MCD levels			10
	small subcounty levels			13

Each database can occur for several geographic levels, for example level=STATE (state totals) and level=COUNTY80 (1980 Census counties).

For each database at each of its available geographic levels, the full document lists:

Code: unique code of SEEDIS database.

Title: name of SEEDIS database.

Level: name of SEEDIS geographic level, for example COUNTY.

Scope: geographic coverage of this database at this Level, for example US.

Areas: number of geographic areas in this database for this Level and Scope.

Nde: number of data elements (fields) in this database. This number does not depend on Level. The number of data values is equal to Areas*Nde.
