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:


RBIRTH2003
(BIRTH2003/((POPESTIMATE2002 + POPESTIMATE2003)/2))*1000

RDEATHS2003
(DEATH2003/((POPESTIMATE2002 + POPESTIMATE2003)/2))*1000

RINTERNATIONALMIG2003
(INTERNATIONALMIG2003/((POPESTIMATE2002 + 
POPESTIMATE2003)/2))*1000

RINTERNALMIG2003
(INTERNALMIG2003/((POPESTIMATE2002 + POPESTIMATE2003)/2))*1000

RNATURALINC2003
((BIRTH2003 – DEATH2003)/((POPESTIMATE2002 + 
POPESTIMATE2003)/2))*1000

RNETMIG2003
((INTERNATIONALMIG2003 + INTERNALMIG2003)/((POPESTIMATE2002 + 
POPESTIMATE2003)/2))*1000
