Recently approved General Assembly redistricting plans will lead to changes in voting districts for thousands of residents across the region and state while others will see no discernible differences.

For instance, residents in Brookfield, Monroe, Oxford, Middlebury will see no change in their district lines, while others who live in Bethel, Danbury, Newtown, Southbury and Woodbury, will see varying amounts of revisions.

However, because district lines cross municipalities, even if a town doesn't experience a change, a district that includes part of the town is likely to see changes. For instance, all of Brookfield will remain in the 107th District, however, that district, now represented by Republican Rep. David Scribner, has been revised to include a piece of Danbury as well as a different swath of Bethel.

The changes were prompted by new census numbers that show shifts in population, and were negotiated by a bipartisan Reapportionment Commission. In determining the change, members began in the northeast quadrant of the state and worked their way across the state, according to co-chairman Rep. Larry Cafero (R-142).

Cafero cited several constraints in the process that fueled the decisions made, although some officials also have said that bipartisan political haggling may have played a role in the process.

The changes only have been approved for General Assembly districts. Revisions also are expected to be made to U.S. congressional districts, although an agreement likely won't arrive until Dec. 21, a deadline extension recently approved by the Connecticut Supreme Court, media outlets were reporting.

Av Harris, a spokesman for the Secretary of State, said that registrars of voters in every town have been informed of what, if any changes, to their respective General Assembly districts. Those registrars will be required to inform the electorate of changes to the districts as well to voting precincts.

For now, here's a list of maps showing the new district lines in several communities:

• Brookfield: House and State
• Bethel: House and State
• Danbury: House and State
• Middlebury: House and State
• Monroe: House and State
• Naugatuck: House and State
• Newtown: House and State
• Oxford: House and State
• Southbury: House and State
• Woodbury: House and State

The changes only will affect state representation and have no impact on municipal elections.

Still, residents, such as Linda Wesley, who lives in a part of Newtown that is being moved to the 2nd house district from the 106th, said she is somewhat concerned that the 2nd district now covers four towns – Bethel, Danbury, Newtown and Redding – as opposed to 106th, which solely encompasses Newtown.

"That makes a difference," she said. "The probably don't care about Newtown that much."

Rep. Dan Carter (D-2) has said he is confident that if re-elected, he will be able to represent everyone living in the district, including Newtown.

Correction: Oxford will see no change in its House of Representatives District 131, though its neighbor, Southbury, will have that district line slightly altered. An earlier version of this article provided conflicting information on what would happen in Oxford.
