How many factories, farms and power plants per citizen

The questions every Soviet Republic player asks sooner or later: how many people does one food factory feed, how many fields does that factory need, and how much power does a new district draw? This page answers them with ratios worked out from the official wiki's building figures and a player-reported sample of citizen consumption. For your own numbers, use the citizen consumption calculator and the production chain calculator.

What 10,000 citizens use

A Steam forum post from October 2021 summarises the yearly totals of one 109,478-citizen republic, relayed from a Reddit discussion. Scaled to 10,000 citizens:

The sample predates version 1.0, so treat it as a starting point and check your own shop statistics once the city is running. The wiki's citizens page gives a second angle: a citizen takes 1.5 kg of food per shopping trip. At 124.4 kg a year, that is roughly one food trip every four or five days.

How many citizens per food factory

A fully staffed food factory (170 workers) turns 42 t of crops into 20 t of food a day, which is 7,300 t a year. Divided by 124.4 kg per citizen, that is about 58,700 citizens on paper. Players on the Steam forum put it at about 40,000 people per food factory in practice, well under the paper figure. Plan toward the forum number and watch the shop shelves.

How many fields per food factory

Food takes 2.1 t of crops per tonne (42 in, 20 out). One factory at full output needs 42 t of crops a day, or 15,330 t a year. The wiki lists a big field at 300 t per harvest at 100% fertility, and with seasons on you get one harvest a year, so a food factory needs about 51 big fields to run on home-grown crops. That matches a forum player's own count of 51.06 big fields. Medium fields (100 t) and small fields (33 t) need three and nine times as many. This is why many players import crops early and only build farms once they have spare workers and land.

Other consumer goods

• Alcohol: a distillery (100 workers) makes 6 t a day from 30 t of crops, which is 5 t of crops per tonne of alcohol. At 9.1 kg per citizen a year, one distillery covers about 240,000 citizens, so a smaller republic will have alcohol left over to export or store.
• Clothes: a clothing factory (80 workers) makes 1.2 t a day from 2.4 t of fabric, enough for roughly 94,000 citizens. A fabric factory makes 5 t of fabric a day from 20 t of crops and 0.5 t of chemicals, so one fabric factory feeds two clothing factories.
• Meat: a livestock farm (50 workers) turns 20 t of crops into 10 t of livestock a day. The wiki has no slaughterhouse figures yet, so the livestock-to-meat step is not covered here.

Power and water per resident

From the wiki's residential buildings table, almost every apartment block uses about 0.045 m³ of water per resident per day at most. Power is about 0.06 MWh per resident per day for blocks of 50 or more residents. Small blocks cost more, because each one draws at least 3.0 MWh a day however few people live in it. In big prefab blocks, 10,000 residents draw up to about 600 MWh a day, less than half the 1,400 MWh a coal power plant makes. Heat in GJ is not listed per building on the wiki, so size heating plants from the in-game demand with the power and heating calculator.

A planning checklist for a 35,000-citizen town

• 1 food factory, plus either crop imports or about 51 big fields.
• 1 clothing factory and 1 fabric factory (or imported fabric).
• 1 distillery, most of its output for export.
• Up to about 2,100 MWh of power a day for housing in large blocks, before shops and industry, which is two coal plants.
• About 1,600 m³ of drinking water a day for the flats alone.

Building the farms behind those factories is covered in the farm setup guide, and every building's raw figures are in the buildings table.
