It's a regionalism to use "any more" to mean "nowadays." It's supposed to be used in a negative sentence, e.g. "Nobody wears sneakers any more." But there are parts of the country where people will say, "Any more, everybody gets up early." Which regions are they?
Wikipedia lists several regions:
Positive anymore occurs in some varieties of North American English, especially in the Midlands variety spoken in parts of Pennsylvania, Ohio, Indiana, Illinois, Kansas, New Jersey, and Missouri; its usage extends to Nevada, Utah and some other western U.S. states.
Positive anymore also occurs in parts of Ireland and Northern Ireland.
Some linguists theorize that the North American usage derives from Irish or Scots-Irish sources.
For a better picture, the Harvard Dialect Survey collected data and made maps for the US:
