Fact check: What years did illinois redraw district maps

1. Summary of the results

Based on the analyses provided, Illinois most recently redrew its congressional district maps in 2021 ^{[1] [2] [3]}. This redistricting followed the standard decennial process that occurs after the U.S. Census, which was conducted in 2020 ^[4]. The 2021 redistricting has been characterized as an example of partisan gerrymandering that favored Democrats ^[3].

The sources consistently confirm that Illinois' current congressional map was adopted in 2021 ^{[2] [5]}, with Republican lawmakers criticizing the process ^[1]. However, none of the analyses provide a comprehensive historical timeline of all the years Illinois has redrawn its district maps beyond this most recent redistricting cycle.

2. Missing context/alternative viewpoints

The analyses reveal several important pieces of context missing from the original question:

• Mid-decade redistricting possibility: Illinois Governor JB Pritzker has not ruled out redrawing congressional maps again before the next scheduled redistricting cycle, potentially in response to similar efforts by other states like Texas ^{[6] [1]}.
• Partisan nature of redistricting: The 2021 Illinois redistricting was specifically designed to favor Democrats and has been criticized as partisan gerrymandering ^{[3] [1]}.
• National redistricting context: Illinois' redistricting decisions are being influenced by actions in other states, particularly Texas's push to redraw maps to add Republican House seats before 2026 ^{[7] [1]}.
• Standard redistricting cycle: The analyses indicate that redistricting typically occurs after each decennial census ^[3], but don't provide the complete historical pattern for Illinois specifically.

3. Potential misinformation/bias in the original statement

The original question itself does not contain misinformation or bias - it's a straightforward factual inquiry. However, the question's scope may be too narrow as it focuses only on historical redistricting years without acknowledging the current political dynamics surrounding potential mid-decade redistricting.

The analyses suggest that focusing solely on past redistricting years misses the immediate political relevance of Illinois potentially redrawing maps again in response to other states' actions ^{[6] [1]}. This omission could lead to an incomplete understanding of Illinois' current redistricting landscape and the political motivations driving potential future map changes.
