The data are in a single ASCII file in DOS format, which is zipped in the

The data used in this paper were originally used in

  A.C. Cameron, P.K. Trivedi, F. Milne and J. Piggott (1988), "A 
  Microeconometric Model of the Demand for Health Care and Health Insurance
  in Australia", Review of Economic Studies, Vol.55, 85-106.

These data were also used in illustrative examples in

  A.C. Cameron and P.K. Trivedi (1998), Regression Analysis of Count 
  Data, Econometric Society Monograph No.30, Cambridge University Press.

The data were obtained from:

  http://cameron.econ.ucdavis.edu/racd/racddata.html

where further details can be obtained (see also the R.E.Stud. (1988) 
article for details on these data). The file is called racd3.asc.

The following is a summary of the data description provided by 
Colin Cameron at the address above (note that some variables are
renamed in the R.E.Stud. (1988) article).

File racd3.asc has 5190 observations and 19 variables.

Variables are:
    SEX,AGE,AGESQ,INCOME,LEVYPLUS,FREEPOOR,FREEREPA,
    ILLNESS,ACTDAYS,HSCORE,CHCOND1,CHCOND2,
    DOCTORCO,NONDOCCO,HOSPADMI,HOSPDAYS,MEDICINE,PRESCRIB,NONPRESC;

Each observation takes one line (80 columns) and is formatted as:
    F3.0,F5.2,F7.4,F5.2,15F4.0 
      
This dataset is not a representative sample of Australians, as it 
oversamples young and old. In particular, use of health services may be 
overstated.

This is because, while the original sample of 40,650 individuals 
from the A.B.S. 1977-78 Australian Health Survey is representative, 
the sample used here is restricted to single people over 18 years of age.
