The 9th millennium BC spanned the years 9000 through 8001 BC. This marks the beginning of the Neolithic period.

Agriculture spread throughout the Fertile Crescent and use of pottery became more widespread. Larger settlements like Jericho arose along salt and flint trade routes. Northern Eurasia was resettled as the glaciers of the last glacial maximum retreated. World population at this time was more or less stable, at Mesolithic level reached during the Last Glacial Maximum, at roughly 5 million.[1]

Subdivision of the Quaternary Period according to the ICS, as of January 2020.[4]

For the Holocene, dates are relative to the year 2000 (e.g. Greenlandian began 11,700 years before 2000). For the beginning of the Northgrippian a date of 8,236 years before 2000 has been set.[5] The Meghalayan has been set to begin 4,250 years before 2000.[4]

'Tarantian' is an informal, unofficial name proposed for a stage/age to replace the equally informal, unofficial 'Upper Pleistocene' subseries/subepoch.

In Europe and North America, the Holocene is subdivided into Preboreal, Boreal, Atlantic, Subboreal, and Subatlantic stages of the Blytt–Sernander time scale. There are many regional subdivisions for the Upper or Late Pleistocene; usually these represent locally recognized cold (glacial) and warm (interglacial) periods. The last glacial period ends with the cold Younger Dryas substage.
