Data includes measurements on mortality rate and explanatory variables (air-pollution, socio-economic and meteorological) for 60 US cities in 1960. This data was originally published in McDonald, G.C. and Schwing,
R.C. (1973) 'Instabilities of regression estimates relating air pollution
to mortality', Technometrics, vol.15, 463-482. It was redistributed through Carnegie Mellon University's StatLib (lib.stat.cmu.edu). Brief codebook notes that it is heavily used for research in ridge regression.PREC (Average annual precipitation in inches) -- JANT (Average January temperature in degrees F) -- JULT(Average July temperature in degrees F) -- OVR65 (Percentage of 1960 SMSA population aged 65 or older) POPN (Average household size) -- EDUC (Median school years completed by those over 22) -- HOUS (Percentage of housing units which are found and with all facilities) -- DENS (Population per sq. mile in urbanized areas, 1960) -- NONW (Percentage of non-white population in urbanized areas, 1960) -- WWDRK (Percentage employed in white collar occupations) -- POOR (Percentage of families with income <$3000) -- HC (Relative hydrocarbon pollution potential) -- NOX (Relative nitric oxide pollution potential) -- SO@ (Relative sulphur dioxide pollution potential) -- HUMID (Annual average percentage relative humidity at 1 p.m.) -- MORT (Total age-adjusted mortality rate per 100,000)Available as Microsoft Excel workbook (xslx); comma separated values (csv) and original plain text.Data set was downloaded with permission from the Carnegie Mellon StatLib (http://lib.stat.cmu.edu/datasets/pollution)Data set includes original text manifest and a small codebook explaining the 16 variables
