PORTLAND, Ore. (TheStreet) -- Yes, you've been seeing seasonal aisles full of Halloween candy, decorations and costumes in stores and supermarkets since at least Labor Day. No, it's not doing a single thing to boost Halloween's profile among retail holidays.According to the folks at market research firm IBISWorld, Halloween spending in the United States is expected to grow to $7.63 billion this year from $7.41 billion in 2010. That's impressive when compared with the $5.77 billion U.S. consumers spent on Halloween at the beginning of the recession in 2008, but just less than half of the $13.2 billion spent on Father's Day this year.

Roughly 158 million consumers say they plan to celebrate Halloween this year, down from 170 million last year. In total, they plan to spend about $75 each on Halloween, down from an average of nearly $80 per shopper last year. WMT) and Target ( TGT) to Kroger ( KR) and Safeway ( SFY) . At a time the balance of Halloween spending is shifting toward adults -- with the $1.2 billion U.S. consumers plan to spend on adult costumes overshadowing the $1 billion they'll spend on kids' outfits -- there should be more money in the Halloween goody bag than ever. At least this year, however, a stagnant economy and equally intractable Congress are the scariest elements Halloween has to offer -- and consumers have lost enough to both already. -- Written by Jason Notte in Portland, Ore. >To contact the writer of this article, click here: Jason Notte. >To follow the writer on Twitter, go to http://twitter.com/notteham. >To submit a news tip, send an email to: email@example.com.
