Recessions and expansions, consumer finance, pro-government militias, pollination and atomic gardening.

Recessions and expansions. The United States has no official definition of a recession, but many observers turn to nongovernmental organizations National Bureau of Economic Researchwhose Business Cycle Dating Committee attempts to determine “the dates of the peaks and troughs that frame economic recessions and expansions”. The committee publish a table and data files listing these dates for dozens of cycles since the mid-1800s. But be prepared to wait: “Our determination of the date of the trough in April 2020 took place 15 months after this date, in July 2021. Previous determinations have taken between 4 and 21 months.” [h/t USAFacts]

The most recent edition surveyed 5,783 families between May 2019 and April 2020. Related: Moritz Kuhn et al.
