If the mark of a successful town is more people coming than leaving, Worthington might be one of the most successful in the Midwest.
Population and economic growth have generally been hard to come by in rural Minnesota. But Worthington since 1990 has surged from fewer than 10,000 residents to more than 13,000. On a two-day trip to Worthington last month, there was talk the population may soon exceed 14,000.
The story here, of course, is how all that growth is due to immigrants, about a third of the people of Worthington now.
The invitation to tag along on a trip to hear about this success story came from Minneapolis Federal Reserve Bank President Neel Kashkari, just another of his regular visits in the six-state district served by the Minneapolis Fed.
Kashkari took pains to always say in Worthington that he came to listen, not preach, although he delivered an unmistakable message just by coming to town.
He's in favor of economic growth. Welcoming immigrants is one good way to get that.
Kashkari's explanation was really just orthodox economics. The basic recipe for long-term growth is simple: more people working and also more machines and technology working.
In many rural areas, more people working is becoming a mission impossible, as population growth stagnates or slips and the people who remain age out of the workforce. In Lac qui Parle County in western Minnesota, the population since 1960 has fallen by about half, and half the people remaining in the county are 50 or older, according to the latest census figures.
