The key for region code is as follows:

        0 = United States Total
        1 = Northeast
        2 = Midwest
        3 = South
        4 = West

The key for division code is as follows:

        0 = United States Total
        1 = New England
        2 = Mid-Atlantic
        3 = East North Central
        4 = West North Central
        5 = South Atlantic
        6 = East South Central
        7 = West South Central
        8 = Mountain
        9 = Pacific


Calculation of the Rates for the period are as follows:


RBIRTH2002
(BIRTH2002/((POPESTIMATE2001 + POPESTIMATE2002)/2))*1000

RDEATHS2002
(DEATH2002/((POPESTIMATE2001 + POPESTIMATE2002)/2))*1000

RINTERNATIONALMIG2002
(INTERNATIONALMIG2002/((POPESTIMATE2001 + 
POPESTIMATE2002)/2))*1000

RINTERNALMIG2002
(INTERNALMIG2002/((POPESTIMATE2001 + POPESTIMATE2002)/2))*1000

RNATURALINC2002
((BIRTH2002 – DEATH2002)/((POPESTIMATE2001 + 
POPESTIMATE2002)/2))*1000

RNETMIG2002
((INTERNATIONALMIG2002 + INTERNALMIG2002)/((POPESTIMATE2001 + 
POPESTIMATE2002)/2))*1000
