Seat allocation, sometimes written as seatallocation, is the process of assigning a limited number of seats to competing demands or users within a system, aiming to meet policy, efficiency, and fairness objectives. It appears in political representation, transportation and events, and venue or classroom management.

In political contexts, seat allocation distributes legislative seats among parties or groups after an election, based on votes or population. Apportionment methods determine how to convert votes into seats. Common methods include highest averages (Jefferson/D'Hondt, Webster/Sainte-Laguë) and largest remainder (Hamilton). The process typically involves establishing the total number of seats, calculating quotas, allocating initial seats, distributing remaining seats, and applying tie-break rules. Regional or demographic constraints and thresholds may influence results.

In transportation and events, seat allocation assigns seats to passengers, attendees, or groups. Airlines and rail operators use bookings, fare classes, and preferences to offer seat assignments, sometimes reserving seats for families or accessibility. The aim is to optimize occupancy, revenue, and service quality, while respecting constraints like safety, legroom, or group seating. Theatres, stadiums, and venues allocate seats based on ticket purchases, price bands, and accessibility needs, using seating charts and booking systems.

In computing, seat allocation is treated as an optimization or allocation problem, often solved with algorithms and software. Models consider constraints such as adjacency, grouping, and accessibility; objectives may include maximizing utilization, minimizing gaps, or balancing equity.

Governance and concerns: Seat allocation is governed by laws, regulations, and policies to promote transparency and fairness. Debates arise over proportionality, gerrymandering risk, or discrimination. Reapportionment or redistricting may occur periodically in political systems to reflect population changes.
