There were 1.77 errors per game in 1970. That number gradually dropped to 1.71 in 1980, 1.51 in 1990, 1.42 in 2000, and 1.25 in 2010. Clearly though, that decline has accelerated in recent years, and MLB is on pace to post its lowest error rate in history this season. It's all bookkeeping that has no real impact on the action on the field. It is a rather significant shift in a short period of time though.
2019: 1.19 errors per game (between the two teams)
2020: 1.17
2021: 1.08
2022: 1.06
2023: 1.01
