+=======================================================================================
+Section 1
+=======================================================================================
+
+The following is a definition of:  LOCAL AREA UNEMPLOYMENT STATISTICS (LA)
+
+Survey Description:  Labor force and unemployment estimates for states and
+local areas are developed by state workforce agencies to measure local labor
+market conditions under a federal-state cooperative program.  The Department
+of Labor develops the concepts, definitions, and technical procedures which
+are used by state agencies for preparation of labor force and unemployment
+estimates.
+
+These estimates are derived from a variety of sources, including the Current
+Population Survey, the Current Employment Statistics survey, the Quarterly
+Census of Employment and Wages, various programs at the Census Bureau, and
+unemployment insurance claims data from the state workforce agencies.
+
+To establish uniform labor force concepts and definitions in all states and
+areas consistent with those used for the U.S. as a whole, monthly national
+estimates of employment and unemployment from the Current Population Survey
+are used as controls (benchmarks) for the state labor force statistics.
+
+Summary Data Available:  Monthly labor force and unemployment series are
+available for approximately 8,300 geographic areas, including cities over
+25,000 population, counties, metropolitan areas, states, and other areas.
+
+For each area, the following measures are presented by place of residence:
+
+	* Total civilian labor force,
+	* Total number of people employed,
+	* Total number of people unemployed, and
+	* Unemployment rate
+
+For states, three additional measures are available:
+
+	* Civilian noninstitutional population,
+	* Labor force participation rate, and
+	* Employment-population ratio
+
+These series begin in January 1976 for statewide data and January 1990 for
+most substate areas.
+
+Frequency of Observations:  Data are monthly in all cases.
+
+Annual Averages:  Annual averages are available for not-seasonally-adjusted
+series.
+
+Data Characteristics:  Rates and ratios are expressed as percents with one
+decimal place.  Levels are measured as individual persons (not thousands) and
+are stored with no decimal places.
+
+Updating Schedule:  With each issuance of preliminary data for the latest 
+month, revisions to estimates for the prior month also become available.  In 
+addition, annual revisions typically result in updates to data for the
+preceding five years by mid-April of the following year.
+
+Other historical revisions occur periodically:  Administrative changes may
+require that data for new areas be collected or that an existing series be
+dropped.  Also, some series ID codes may change.

+Section 3
+=======================================================================================
+
+The definition of a time series, and its relationship to and the interrelationship
+among series, data, and mapping files are detailed below:
+
+A time series refers to a set of data values observed over an extended period of
+time at consistent intervals (e.g., monthly, quarterly, semi-annually, annually).  
+BLS time series data are typically produced at monthly intervals and represent data 
+ranging from a specific consumer item in a specific geographical area whose price 
+is gathered monthly to a category of worker in a specific industry whose employment
+is being recorded monthly, etc.
+
+The files are organized such that data users are provided with the following set of
+files to use in their efforts to interpret data files:
+
+a)  a series file (only one series file per survey)
+b)  mapping files
+c)  data files
+
+The series file contains a set of codes which, together, compose a series 
+identification code that serves to uniquely identify a single time series.  
+Additionally, the series file contains the following series-level information:
+
+a) the period and year corresponding to the first data observation
+b) the period and year corresponding to the most recent data observation
+
+The mapping files are definition files that contain explanatory text descriptions
+that correspond to each of the various codes contained within each series
+identification code.
+
+The data file contains one line of data for each observation period pertaining to a
+specific time series.  Each line contains a reference to the following:

+a) a series identification code
+b) year in which data value is observed
+c) period for which data value is observed (M13 indicates annual average)
+d) data value
+e) footnote code (if applicable)

+File Structure and Format:  The following represents the file format used to define 
+la.series.  Note that the Field Numbers are for reference only; they do not exist 
+in the database.  Data files are in ASCII text format.  Data elements are separated 
+by tabs; the first record of each file contains the column headers for the data
+elements stored in each field.  Each record ends with a new line character.

+
+The series_title [Unemployment Rate: Balance of California, state less Los Angeles-
+Long Beach-Glendale MD (S)] is a concatenation of the measure, area text, and 
+seasonal adjustment values:
