The area around Alexandreia has the greatest production of peaches in Greece and apples, pears, tobacco, and cotton are also grown at large.

[9] According to this tax list, Gidas would be charged with 1900 aspers, which would render it the largest village in the area at that time with a probable population of 400 people.

[10] There are numerous mentions of Gidas in the following centuries, including the visit of the local Church of St. Athanasios by Cosmas the Aetolian in 1775 as a part of his missionary tours.

[9] As a rural area and feudal property, Gidas's people were mostly peasants and animal husbandmen, although there were also merchants trading all local kinds of commodities, and there was a school.

During the 19th century, the economic ascent of Thessaloniki and of the other urban centers of Macedonia coincided with the cultural and political renaissance of the Greeks.

Meanwhile, the Ottomans had resorted to military rule, which provoked further resistance, and also led to economic dislocation and accelerated population decline.

Ottoman landholdings, previously fiefs held directly from the Sultan, became hereditary estates (Chifliks), which could be sold or bequeathed to heirs.

[12] Despite the general agitations in Greece and Macedonia as well as the redeployment of Slavic and Albanian forces and populations in the area, the Greeks living in Roumlouki were isolated and secured from the outer conflicts, and as thus they preserved their traditional lifestyle, their morals and customs and their costumes.

[16][17] From that cadastre, it is known that at least 150 families, of mostly farmers and shepherds, resided in Gidas, and there were also a few shops and an inn, meeting the needs of the dwellers and travelers.

The next day, on October 18, the VII Cavalry Division of the Greek Army entered the town freeing the people of Gidas.

After the Greco-Turkish War of 1919–1922 and the population exchange between Greece and Turkey, 40 refugee families settled in Gidas and the need for their rehabilitation led to a second distribution of the land to the people.

The on end spatial arrangement led to the continuously unfair dispersion of land to the people, which was resolved with the fair distribution of 3 acres (1 ha) to each dweller in 1937.

[12][25] After the draining of the lake of Giannitsa in 1932, thousands of fertile fields became available, which supported the local people and led to the general development of the area.

In addition to the local development, the all along current location of the Roumlouki fields, serving as a junction between Thessaloniki and the Western Macedonia as well as the Southern Greece, constituted an attraction for internal migration and a push for strong economic progress.

During the same period, a large number of Romani populations started appearing in Gidas, and today they constitute the largest minority group in Alexandreia.

More specifically, its economy is based on the abundance of agricultural products, namely cotton, peaches, sugar beets, tobacco, apricots, apples, corn, cereals, and numerous vegetables, that leads to the powerful, local, agricultural production, which is largely exported, while a major part of it drives the local industrial enterprises.

The sewerage network, whose construction lasted for a long time, is complete and functional, which is expected to be a milestone for the further development of the city.
