Census Data Sets for the Expected Survival and Person Years Functions

Description:

     Census data sets for the expected survival and person years
     functions

Usage:

     data(ratetables)
     survexp.uswhite<-survexp.usr[,,"white",]

Details:

     us total United States population, by age and sex, 1960 to 1980.

     uswhite United States white population, by age and sex, 1950 to
          1980. This is no longer included, but can be extracted from
          'survexp.usr' as shown above.

     usr United States population, by age, sex and race, 1960 to 1980. 
          Race is white, nonwhite, or black.  For 1960 and 1970 the
          black population values were not reported separately, so the
          nonwhite values were used.

     mn total Minnesota population, by age and sex, 1970 and 1980.

     mnwhite Minnesota white population, by age and sex, 1960 to 1980.

     fl total Florida population, by age and sex, 1970 and 1980.

     flr Florida population, by age, sex and race, 1970-1980.  Race is
          white, nonwhite, or black.  For 1970 the black population
          values were not reported separately, so the nonwhite values
          were used.

     az total Arizona population, by age and sex, 1970 and 1980.

     azr Arizona population, by age, sex and race, 1970-1980.  Race is
          white versus nonwhite.  For 1970 the nonwhite population
          values were not reported separately. In order to make the
          rate table be a matrix, the 1980 values were repeated. 
          (White and non-white values are quite different).

     Each of these tables contains the daily hazard rate for a matched
     subject from the population, defined as -log(1-q)/365.24 where q
     is the 1 year probability of death as reported in the original
     tables. For age 25 in 1970, for instance, p = 1-q is is the
     probability that a subject who becomes 25 years of age in 1970
     will achieve his/her 26th birthday. The tables are recast in terms
     of hazard per day entirely for computational convenience. (The
     fraction .24 in the denominator is based on 24 leap years per
     century.)

     Each table is stored as an array, with additional attributes, and
     can be subset and manipulated as standard S arrays. Interpolation
     between calendar years is done "on the fly" by the survexp
     routine. 

     Some of the deficiencies, e.g. 1970 Arizona non-white, are a
     result of local conditions.  The data probably exists, but we
     don't have a copy it in the library.

     The tables have  been augmented to contain extrapolated values for
     1990 and 2000.  The details can be found in Mayo Clinic
