[Link] US Egg Production Data Set

The Hu­mane League Labs has pub­lished a data set and re­port in a pro­ject ti­tled US Egg Pro­duc­tion Data Set that com­piles an anal­y­sis-ready data on US egg pro­duc­tion (with a fo­cus on cage-free hous­ing) and clar­ifies ter­minol­ogy. I am happy to an­swer any ques­tions and re­ceive feed­back, as we hope these prod­ucts will be helpful to the wider re­search com­mu­nity.

Ex­ec­u­tive Sum­mary: Track­ing the ca­pa­bil­ity of the egg pro­duc­tion in­dus­try to sup­ply the food in­dus­try with enough cage-free eggs to meet re­tailers’ and restau­rants’ an­i­mal welfare com­mit­ments is im­por­tant to in­dus­try groups and farm an­i­mal ad­vo­cacy or­ga­ni­za­tions al­ike. In this pro­ject, we syn­the­size an anal­y­sis-ready data set that tracks the sup­ply of cage-free eggs rel­a­tive to the over­all sup­ply of table eggs in the United States. The data set is based on United States Depart­ment of Agri­cul­ture (USDA) re­ports pub­lished monthly from Septem­ber 2016 to pre­sent, with aux­iliary an­nual data from De­cem­ber 2007 to De­cem­ber 2015. The data set will be up­dated monthly as new USDA re­ports are re­leased. We sup­ple­ment these data with defi­ni­tions and a tax­on­omy of egg prod­ucts drawn from USDA and in­dus­try pub­li­ca­tions. The data in­clude flock size and egg pro­duc­tion of cage-free hens as well as all table egg lay­ing hens in the US, col­lected to un­der­stand the im­pact of the in­dus­try’s cage-free tran­si­tion on hens. Ini­tial anal­y­sis of egg pro­duc­tion trends shows that, at the time of pub­li­ca­tion of this re­port, 20.3% of all table egg lay­ers lived in cage-free sys­tems. This figure rep­re­sents an in­crease of 10.2 per­centage points be­tween Au­gust 2016 to June 2019, with an in­crease of 17.1 per­centage points over the en­tire sam­ple pe­riod of 2007 to June 2019.
