the counter examples are things like roads, pipes, wires, and Public transit which make to
up a high percent of city and state budgets and scale with density.
These examples are fair. At the provincial level Transport, Pipes and Wires all are small enough expenditures to not warrant their own category breakdown in the budget and are lumped into a 14.6% of budget other category.
At the city level it's tricky because the breakdown my city provides in the budget separates into capital and operating rather than other categories. From what I can tell from the 50 page report, water pipes cost approximately 25% of budget and transport costs approximately 5%. Wires aren't listed in enough details to get an estimate.
My best sense from the numbers in the breakdown is the expenses for my suburb breakdown into roughly 60% per capita items, and 40% per area items. So 60% of our budget gets more expensive as you add people with low per capita taxation and 40% gets cheaper as you add more density.
How old is your community? Because road expenses are relatively low when they're new, but many communities aren't being fiscally responsible enough to budget appropriately for road maintenance.
