The confounding variable is how developed a country is. It negatively influences both stork pairs (storks in Europe mostly live in old-style individual farming countryside) and birth rates.

The confounding variable is how large a country is (both size and population - two variables that are themselves related). The papers “birth rate” is absolute: thousands of births per year in that country. It should be number of births per woman of childbearing years. Likewise, the number of stork pairs is the absolute number in the country. It should be absolute number per square kilometer, or per square kilometer of stork habitat. A geographically larger country will (generally) have more people and more storks. Edit: there are also some outliers heavily influencing things: Poland and Turkey have tons of storks. Belgium, Denmark, Holland, and Switzerland don’t seem to have native storks.

  > Poland and Turkey have tons of storks. Belgium, Denmark, Holland, and Switzerland don’t seem to have native storks. This is the development factor I wrote about :) Storks in Europe live in symbiosis with individual farmers. As countries switch from millions of small farmers to thousands of massive industrialized farms - stork populations dwindle. This is how it looks like: https://pl.wikipedia.org/wiki/Stary_Brus#/media/Plik:Stary_Brus_centrum.jpg https://pl.wikipedia.org/wiki/Stary_Brus#/media/Plik:Stary_B... Almost every house has its stork nest, people provide the scaffolding for the nest (usually on the house roof or on powerline pylons). Storks eat small rodents, insects and other pests (for example whenever farmers are plowing storks go behind the tractor and eat larva that are uncovered).

    That corporate farms fail to provide stork nestage is a fail.
    - ajuc 5y ago
      One corporate farm would have to provide hundreds nests to offset the individual farmers they replaced.

        OK. So, provide. Mandate providing.

  Storks in Denmark have dwindled to 1-2 pairs from a larger population. This is of course also projected in the birth rate: https://www.macrotrends.net/countries/DNK/denmark/birth-rate https://www.macrotrends.net/countries/DNK/denmark/birth-rate

The human birth rate also declines the more developed a country is (per person, at least)

  That's the point?

    Ah I see, must have misread the first time round.
