两个选区，一个有 15 万选民，另一个只有 3 万，却各自只选出一名议员。那么，小选区里每一票的「分量」，是不是比大选区更重？

这个问题，正是「选区划分」争论的核心。

什么是选区划分

选区划分（delineation / persempadanan），是决定每个选区地理边界的过程。在马来西亚，这由选举委员会（SPR）依据联邦宪法规定的程序进行，通常每隔若干年检讨一次，并需经国会通过。

划线要考虑人口、社区完整性、地理等因素。看似技术性，实则影响深远。

两个关键概念

  • 选区人数不均（malapportionment）：不同选区的选民人数差距很大。当小选区和大选区各选一名议员，小选区选民的相对影响力就更高。
  • 不公正划分（gerrymandering）：刻意设计边界，让某方更容易赢得较多议席。这是一个被广泛讨论的公平性议题。

宪法本身也提到，应尽量让选区选民人数大致相近，但允许因地理、社区等因素有合理差异——差异到什么程度算「合理」，正是争论所在。

一个具体的例子

假设把一个原本势均力敌的地区，重新划成边界，让支持某方的选民集中到少数几个选区（那几区他们大胜但只算几席），而在其余选区变成少数（每区小输）。总票数没变，议席结果却可能大不同。这就是为什么「怎么画线」和「投给谁」一样重要。

为什么这和你有关

选区边界决定了你的一票落在哪个选区、和谁一起计算、分量有多重。它悄悄地塑造了选举的起跑线。关注划线，就是关注选举是否公平的地基。

公民该知道的事

  • 选区划分由 SPR 依宪法程序进行，重划建议须经国会通过。
  • 划分过程通常设有**公众展示与反对（representation）**的窗口——公民与团体可依程序提出意见。
  • 「选区人数差异」有其合法考量（如照顾乡区），但差异过大是否公平，是可公开讨论的议题。

核心带走点

选举的公平，不只发生在投票那一天，也发生在「画线」那一刻。看懂选区划分，你就看懂了：为什么有人说，选举的一部分胜负，在投票之前就已经被地图决定了一部分。

Two constituencies: one has 150,000 voters, the other just 30,000, yet each elects a single MP. So isn't each vote in the small one "heavier" than in the large one?

That question sits at the heart of the debate over constituency delimitation.

What delimitation is

Delimitation (persempadanan) is the process of setting each constituency's geographic boundaries. In Malaysia this is done by the Election Commission (SPR) under a process set out in the Federal Constitution, reviewed periodically and requiring passage in Parliament.

Line-drawing weighs population, community integrity and geography. It looks technical but runs deep.

Two key concepts

  • Malapportionment: large gaps in voter numbers between constituencies. When a small and a large constituency each elect one MP, voters in the small one have greater relative influence.
  • Gerrymandering: deliberately shaping boundaries so one side more easily wins more seats — a widely discussed fairness issue.

The Constitution itself notes that constituencies should have roughly comparable voter numbers, while allowing reasonable variation for geography and community — and just how much variation counts as "reasonable" is where the debate lies.

A concrete example

Suppose an evenly split area is redrawn so that one side's supporters are packed into a few constituencies (winning big there but only a few seats), while becoming a minority elsewhere (narrowly losing each). Total votes unchanged, seat outcomes potentially very different. That is why "how the lines are drawn" matters as much as "who you vote for."

Why this matters to you

Boundaries decide which constituency your vote falls in, who it's counted with, and how much it weighs. They quietly shape the starting line of an election. Watching delimitation is watching the foundation of electoral fairness.

What a citizen should know

  • Delimitation is done by SPR under a constitutional process, with redelineation proposals requiring passage in Parliament.
  • The process usually has a public display and objection (representation) window — citizens and groups can submit views through the procedure.
  • Differences in voter numbers have legitimate considerations (such as serving rural areas), but whether very large gaps are fair is a matter for open debate.

The takeaway

Electoral fairness happens not only on polling day but at the moment of "drawing the lines." Understand delimitation and you see why some say part of an election's result is decided, in part, by the map before anyone votes.
