Subject: Population Histograms
I'm a neophyte to SPSS and to computing in general (despite the grey hair).
I read with interest today (Feb 9) the thread on Overlaying Multiple Histograms. In particular, Mr. Peck's reply that version 13 enables population pyramids, which I assume is meant like this:
I have version 12.0. I'm also using a file of about 45,000 records, composed of about 15,000 records for the years 2002, 2003, and 2004, with age and sex for each record. The file is being used for Kaplan-Meier analysis of duration in receipt of payment. I thought about trying to run this analysis with age and sex, but wanted to present the general pyramid first. I suppose it's possible to export the data to Excel and change men's ages to negatives (were it only possible in real life!), but the result would ask the reader to ignore the negatives. Ideally there would be some way of presenting all three years on one graph so that the changes can be seen over time, without resorting to animation - for instance a bar graph of 2002, with superimposed lines for 2003 and 2004..
On the way out there front, it would be very interesting to forecast the population changes well into the future; however, I have no idea what function would be needed or is generally accepted for such a relatively small cohort.
Any assistance on any of the issues mentioned would be appreciate.
