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:


RBIRTH2004
(BIRTH2004/((POPESTIMATE2003 + POPESTIMATE2004)/2))*1000

RDEATHS2004
(DEATH2004/((POPESTIMATE2003 + POPESTIMATE2004)/2))*1000

RINTERNATIONALMIG2004
(INTERNATIONALMIG2004/((POPESTIMATE2003 + 
POPESTIMATE2004)/2))*1000

RINTERNALMIG2004
(INTERNALMIG2004/((POPESTIMATE2003 + POPESTIMATE2004)/2))*1000

RNATURALINC2004
((BIRTH2004 – DEATH2004)/((POPESTIMATE2003 + 
POPESTIMATE2004)/2))*1000

RNETMIG2004
((INTERNATIONALMIG2004 + INTERNALMIG2004)/((POPESTIMATE2003 + 
POPESTIMATE2004)/2))*1000
