What drove Maricopa County Arizonas 2020 to 2024 swing?
How Atlas thought about thisflip_analysis

Question interpretation

Analysis of Maricopa County, AZ's partisan swing between the 2020 and 2024 presidential elections — magnitude, sub-geographic concentration, and peer-county context.

Ambiguity notes

  • Interpreting 'drove' as identifying the magnitude of the 2020→2024 margin shift and which sub-geographies within Maricopa showed the largest contributions; causal attribution beyond concentration patterns and peer comparison is not possible from election data alone.
  • Using the (dem-rep)/total margin convention; swing computed as margin_2024 − margin_2020.
  • Peer context included via the peer_group comparison role to contextualize whether the swing is idiosyncratic to Maricopa or part of a broader wave.
