Needs by tier: what every resident needs to upgrade

A residence upgrades when every need category it has (food, public services, fashion, household, culture, marvels) reaches its supply threshold. Each supplied need adds its supply value to its category, so several partly useful needs can add up to the threshold. Upgraded residents keep all needs of the tiers below them, so the tables below list only what each tier adds.

How the threshold works

Each need has a supply value of 1, 2, 4 or 8 in the game data. Most tier 1 needs are worth 1 and most tier 2 needs 2; tier 3 and 4 needs are worth 4 or 8. Anno Union gives two thresholds as examples: the Liberti food threshold is 1, so Sardines or Porridge alone completes it; the Plebeian food threshold is 3, so Sardines and Porridge (1 + 1) fall short and a second chain such as Garum or Bread (2 each) is needed. A service need counts when the residence is inside the service building’s range. Supplying more than the threshold still pays: every need adds residents, income or other attributes to the residence.

Marvels	Equites, Patricians, Nobles, Aldermen, Chanters, Gymnasiarchs

Latium

Plebeians also gain Bread as a regular need; since Update 2.0 it adds 3 residents per residence. Latium has no building for Beer, Cheese, Brooches, Bird Tongues in Aspic, Cloaks, Handmirrors, Chariots or Roast Beef: they come from Albion. The Latium page lists every import with its producer.

Albion

Waders choose a path at tier 2. Mercators and Nobles take Roman goods; Smiths and Aldermen keep Celtic ones. Reaching tier 3 on one path unlocks the other, so both can live in the same province.

Tier	New goods	New services	DLC or item needs
1 Waders	Cockles, Eels, Reed Shoes, Tunics, Garum	Market, Bardic Hearth	–
2 Mercators (Roman)	Bread, Sausages, Brooches, Amphorae, Olive Oil	Grammaticus, Fanum	Soap, Scribing Sets (Dawn of the Delta); Statuettes (Prophecies of Ash)
3 Nobles (Roman)	Bird Tongues in Aspic, Wigs, Togas, Handmirrors, Fine Glass	Aqueduct Cistern, Theatre, Gambling House; marvels Temple and Baths	Wine, Rare Meat Platters, Perfumed Oils (Dawn of the Delta); Loungers (item)
2 Smiths (Celtic)	Cheese, Beer, Trousers, Torcs, Drinking Horns, Clan Shields	Recreation Ground, Fanum	Kollurion, Apotropaic Talismans (Dawn of the Delta)

Garum, Olive Oil, Togas, Fine Glass and Loungers have no Albion producer and come from Latium.

Aegyptus

Aegyptus needs Dawn of the Delta. Threshers choose at tier 2 between the Aegyptian path (Potters, then Chanters) and the Graeco-Roman path (Scribes, then Gymnasiarchs).

Tier	New goods	New services and marvels
1 Threshers	Dates, Porridge, Wesekh Collars, Tunics	Market, Firepit
2 Potters (Aegyptian)	Stuffed Goose, Beer, Shentis, Kollurion, Apotropaic Talismans, Oil Lamps, Drinking Horns	Apothecary, Sanctuary
3 Chanters (Aegyptian)	Kayk, Blue Lotus Tea, Kalasirises, Perfumed Oils, Cloaks, Sistrums, Fine Glass, Handmirrors	Rock Tomb, Theatre, Gambling House; marvels Temple, Observatory, Renovated Pyramids

3 Gymnasiarchs (Graeco-Roman)	Rare Meat Platters, Wine, Bird Tongues in Aspic, Necklaces, Milk of Poppea, Wigs, Ivory Caskets, Loungers	Aqueduct Cistern, Theatre, Gambling House; marvels Baths, Library, Renovated Pyramids

Potters and Chanters also want Statuettes with Prophecies of Ash. Aegyptus imports Drinking Horns, Cloaks, Fine Glass, Handmirrors, Brooches, Bird Tongues in Aspic, Wigs and Loungers from Albion or Latium.

Residents per residence

Every need and service has a Population value. Supplying all base-game needs gives these residents per residence: Liberti 6, Plebeians 13, Equites 23, Patricians 34; Waders 4, Mercators 12, Nobles 20, Smiths 9, Aldermen 18. In Aegyptus, without item-unlocked needs: Threshers 5, Potters 12, Chanters 20, Scribes 13, Gymnasiarchs 20. Each resident page lists the value of every need, its consumption per residence and how many residences one building supplies.

DLC needs in older provinces

Dawn of the Delta adds needs to Latium and Albion residents as well, for example Dates, Kollurion and Scribing Sets for Equites, and Soap for Plebeians and Mercators. The game data ties each of them to the DLC. Needs marked “item” appear only after the named item, such as a festival reward or specialist, is in effect.
