Data fields (in order in which they appear):

VARIABLE				DESCRIPTION

HISP 				     Hispanic origin code
RACE				     Race code
SEX				     Sex code
YEAR				     Year of projection (July 1, 2000 to July 1, 
				     2050)
TOTAL_POP			     Population total (all ages combined) in each 
				     year 
(POP_0, POP_1, ...POP_99, POP_100)   Population age x as of July 1 (columns for ages
				     0, 1, 2, ...98, 99, 100 or more years old)

The key for HISP code is as follows:
	0 = Total
	1 = Not Hispanic
	2 = Hispanic

The key for RACE code is as follows:
 	0 = All races combined

 	1 = White alone
 	2 = Black alone
 	3 = AIAN alone
 	4 = Asian alone
 	5 = NHPI alone
 	6 = Two or more races

	7 = White alone or in combination
 	8 = Black alone or in combination
 	9 = AIAN alone or in combination
 	10 = Asian alone or in combination
 	11 = NHPI alone or in combination

The key for SEX code is as follows:
	0 = Total
	1 = Male
 	2 = Female

NOTE 1: 'In combination' means in combination with one or more other races.  The 
sum of the five race groups (RACE codes 7 through 11) adds to more than the total 
population because individuals may report more than one race.

NOTE 2: The projections generally do not precisely agree with population estimates 
available elsewhere on the Census Bureau website for methodological reasons.  
Where both estimates and projections are available for a given time reference, 
we recommend that you use the population estimates as the measure of the current 
population. 

ABBREVIATIONS: Black = Black or African American; AIAN = American Indian and Alaska 
Native; NHPI = Native Hawaiian and Other Pacific Islander
