Editor's Note: A new version of this interactive is now available, reflecting new maps presented by the federal judges in San Antonio late February. While this version will continue to exist to maintain the link, it is recommended that you use the newer version.

Candidates began filing for the March 6 primary elections Monday, while the state's attorney general asked the U.S. Supreme Court to block legislative and congressional maps drawn by a San Antonio court. But pending any legal intervention, the three court-issued maps (House, Senate and Congress) and the State Board of Education map drawn up by the 82nd Legislature are now in effect.

So what changed? Or, perhaps more importantly, what changed for you? Use the Tribune's new redistricting tool to see if you were moved into a new district over the Thanksgiving weekend.

To use the tool, enter your address in the text box below and then click on the "Where Am I?" button. On the map, a marker will represent your location on each side of the split. The left side represents the old maps used in the 2010 elections. The right side represents the three court-drawn interim maps and the SBOE map. Districts on the map are shaded based on their Texas Weekly Index (TWI), which represents the partisan inclination of voters in that district based on results in the 2008 and 2010 elections. The number is the difference between average Republican and Democratic candidates in each district over the last two elections: A TWI of 17.1 — the state average — means the average Republican candidate beat the average Democrat by that many percentage points in those elections. Districts shaded red are Republican districts; districts shaded blue are Democratic districts.

The data to the right of the map will show your old district and representatives as of the 2010 election in one column and your district and representatives according to the new maps in the other column, along with the TWI score of both. Red numbers indicate Republican districts; blue numbers indicate Democratic districts.
