How long must a person have lived in their election district before being eligible to vote in Illinois?

A person must have lived in their election district for at least 30 days before being eligible to vote in Illinois. This requirement ensures that voters have an established connection to the community in which they intend to cast their ballots, fostering integrity in the electoral process. By mandating a residency period, the law helps to prevent transient individuals from impacting local elections in a manner that may not reflect the interests of the long-time residents of the district. Thus, the 30-day residency requirement is an essential aspect of voter eligibility, aligning with the principles of responsible and informed participation in democracy.
