What were conditions like before the decision in westberry v sanders?

Before the decision in Westberry v. Sanders (1964), many congressional districts in the United States suffered from significant population imbalances, leading to unequal representation in Congress. Some districts had vastly more residents than others, violating the principle of "one person, one vote." This disparity often resulted in overrepresentation for less populated areas and underrepresentation for more populous regions, undermining the democratic process. The case ultimately sought to address these inequities by enforcing more equitable districting practices.
