Different types of electoral systems used worldwide include *first-past-the-post*, *proportional representation*, and *ranked choice voting*. The **first-past-the-post** system awards victory to the candidate with the most votes, commonly used in places like the United States and Canada. In contrast, *proportional representation* allocates seats in the legislature based on the proportion of votes each party receives, aiming for more equitable representation. Additionally, *ranked choice voting* allows voters to rank candidates in order of preference, promoting a more nuanced selection process. Each system has its strengths and weaknesses, impacting political representation and party dynamics.
