The Eastern Roman economy suffered less from the Barbarian raids that plagued the Western Roman Empire. Under Diocletian's reign, the Eastern Roman Empire's annual revenue was at 9,400,000 "solidi", out of a total of 18,000,000 "solidi" for the entire Roman Empire. These estimates can be compared to the AD 150 annual revenue of 14,500,000 "solidi" and the AD 215 of 22,000,000 "solidi". By the end of Marcian's reign, the annual revenue for the Eastern empire was 7,800,000 "solidi", thus allowing him to amass about 100,000 pounds/45 tonnes of gold or 7,200,000 "solidi" for the imperial treasury. Warren Treadgold estimates that during the period from Diocletian to Marcian, the Eastern Empire's population and agriculture declined a bit, but not much. Actually, the few preserved figures show that the largest eastern cities grew somewhat between the 3rd and 5th centuries. By Marcian's reign the Eastern Empire's difficulties seem to have been easing, and the population had probably begun growing for the first time in centuries.
