tl;dr: Your vote really counts!
Each vote in a UK General Election is worth maybe 100,000 - to you and all your fellow citizens taken together. If you really care about the welfare of
everyone affected by actions of the UK government, then it s worth that to you too.
Introduction
It seems a common perception that one vote, in amongst all those millions, doesn t really matter. So maybe it s not worth voting. But, voting is (largely) what determines what the government does - and the government is
big. It s as big as all the people.
If you are the kind of person who cares about what happens to
everyone in your polity and indeed everyone its actions affect, then even your one vote is very important indeed.
A method for back of the envelope calculation
It would be nice to give a quantitative estimate. Many things in our society are measured in money, so let s try taking a stab at calculating the money value of your vote.
The argument I m going to make is this: the government (by which I include the legislature), which is selected by our votes, decides how to spend the national budget.
So, basically, I m going to divide the budget, by the electorate.
UK Parliament
UK Parliamentary elections decide not only the House of Commons, but, through that, the government. The upper house, the House of Lords, has very limited influence. So I think it s fair to regard the Parliamentary election as, simply, controlling that budget.
Being lazy, I m going to use Wikipedia data. We have the
size of the electorate, for 2019, 47.6 million. But your influence isn t shared with the whole electorate, only with the other people who also vote.
Turnout in 2019 was 67.3%. The 2019 budget isn t listed but I ll just average the
2018 and March 2020 figures 842bn and 873bn, so 857 billion. (Strictly speaking I should add up the budgets for the period of the Parliament, but that seems like a lot of effort.)
There s a discrepancy in the timescale we need to account for. Your vote influences the budgets for several years, depending how long it is until the next election. Taking Wikipedia s
list of elections this century there ve been 7 in 24 years. So that s an average of about 3.4y.
So, multiplying it through, we have ( 857b * (24 / 7)) / (47.6M * 67.3%), giving a guess at the value of your UK General Election vote:
92,000.
European Parliament
2022 budget for the European Union (
Wikipedia again) was 170.6 bn.
The last election, in 2019,
had a turnout of 198,352,638. Each EU Parliament lasts 5 years.
The Parliament, however, shares responsibility for the budget with the European Council, which is controlled, ultimately, by national governments. We have to pick a numerical value for the Parliament s share of the influence. Over the past years the Parliament has gradually been more willing to exercise its powers in this area. I m going to arbitrarily call its share 50%.
The calculation, then, is 170.6 bn * 5 * 50% / 198M, giving a guess at the value of your EU Parliamentary Election vote:
2150.
This much smaller figure reflects simply that the EU doesn t spend very much money, for a polity of its size. (Those stories in the British press giving the impression that the EU is massively wasteful are, simply, lies.)
The interaction of this calculation with the
Council s share of the influence, and with national budgets, is a bit of a question, but given the much smaller amounts involved, it doesn t seem worth thinking about that too hard.
Only if you care about other people as much as yourself!
All of this is only true for you if you value and want to help everyone in your society. That includes immigrants, women, unemployed people, disabled people, people who are much poorer or richer than you, etc.
If you think about it in purely personal terms, your vote is hardly worth anything - because while the effect of your vote, overall, is very large, that effect is shared by everyone in your polity. So if you only care about yourself, voting is a total waste of time. The more selfish and xenophobic and racist and so on you are - caring only about people like yourself - the less your vote is worth.
This is why voting is rightly seen as a civic duty. I just spent 30 to courier my EP vote to Den Haag. That only makes sense because I m very willing to spend that 30 to try to improve the spending of the 2000 or so that s my share of the EU budget.
This is a very rough analysis
These calculations neglect a lot of very important things: politics isn t just about the allocation of resources. It s also about values, and bad politics can seriously harm people.
Arguably many of those effects of your vote, are much more important than just how the budget is set and spent.
It would be interesting to see an attempt at a similar analysis but for taking into account life and death questions like hate crime, traffic violence, healthcare, refugees welfare, and so on. I m not sure how to approach that. Maybe some real social scientists have done so? References welcome.
Also, even on its own terms, this analysis is very rough and ready. We haven t modelled the ability of the government to change its tax rates; perhaps we should be multiplying GDP (or some other better measure) by 90% percentile total tax rate amongst countries like this one . The amount of influence that can be wielded by one vote is probably nonlinear in the size of the political faction, but IDK in which direction. In unfair voting systems like the UK s, some people s votes are worth
much more than others. In a very marginal constituency, which is a target seat, your vote might be worth tens of millions. In a safe seat, it might only be worth a few thousand. And in practical terms you don t get to choose precisely the policies you want; you have to pick a party, which is sometimes very much a question of the lesser evil.
So, there is much I haven t modelled. But the key point stands:
Conclusion
Although your vote is diluted by everyone else s votes, together, we control the government, which affects us all. So if you care about the whole of society, the big numbers in the divisor, and the numerator, cancel out.
You can think of your vote as controlling one citizen s worth of government activity.

ASes comes in different sizes and purposes. Like AS749 DoD Network Information Center which holds more than 200 million+ IPv4 addresses for historical reasons or AS23860 Alliance Broadband Services which has 68 thousand+ IPv4 address for purpose of providing consumer Internet.
Similarly, some individuals also run their personal ASN including a bunch of Indians. Most of these Indian ASNs are IPv6 (primary or only) networks run for hobby and educational purposes. I was interested in this data, so complied a list of active ones (visible in the global routing table) from BGP.Tools:
