Box, George E. P.; Hunter, William G.; Hunter, J. Stuart, Statistics for Experimenters, John Wiley & Sons, John Wiley & Sons, Inc., 1978, ISBN: 0-471-09315-7, Page 8. Lars Pallesen found data for storks nets and population for Oldenberg, Germany between 1930 and '36. Data references are cited.
Since the data is strictly correlational, one can use the plot to 'demonstrate' that storks cause/bring babies, or reverse the axes and 'demonstrate' that babies cause storks.

Usually they are described as having been observed in Sweden. I seem to remember one set in a Genstat manual. I have been asked about an unreferenced set I used in an article in abput 1980, although I think it was later. I have been using a version recently to teach abput the Bradfprd Hill criteria.
