A possible start, as sent to someone through email: The data varies considerably state-by-state. Not all states are covered, though most are; we have 40 states and Washington, D.C. now. How far back that data goes also varies. The scraping project is indeed several years old, but some of the states offer historical data going significantly farther back. The data is ... a bit dirty, in the sense that some states report waves of layoffs as separate entries and some as a combination. Even some of the numbers vary, e.g., when the big Yellow shipping company went out of business a few years ago, some states were reporting numbers for their state and some were reporting numbers for the entire country, which may have been something like 18,000. Big Local News would encourage you to think of this data set more as a set of tips that need to be reported and verified out. It can vary from what the state reports (e.g., multiple dates of layoffs are condensed into one date); the states themselves often get it wrong; each state is its own time series of a differing length; and not all states are covered. Oh! And integrated.csv is indeed the file with cleaner data. Note that it is not necessarily sorted in any way.
