It was right back to business yesterday for Danbury Mayor Mark Boughton.  A day after winning reelection to start a 10th term, Boughton held a Task Force meeting about education in the City.  An updated demographics study has been ordered following the unexpected enrollment increase at the start of the new year.  Boughton says there are short and long term problems to address, which could be done through a new Charter School, a new pre-k center to free up room in elementary schools, and building new classrooms.  A study found that most of the increase came from multi-family houses, and about half were from other countries.  The number of English language learners increased 11 percent from the previous year, and about half of those students are new to the district.
