The concentration in France, together with the presence in Belgium, Switzerland and to a lesser extent in other countries, suggests that its most likely origin is in the French-speaking area.

Etymology and Meaning of Decaux
Linguistic analysis of the surname Decaux suggests that it could be a toponymic surname or related to a place name. The structure of the surname, which begins with the prefix "De-", is common in surnames of French and Spanish origin, and generally indicates origin or belonging to a place. The ending "-caux" or "-aux" in Old French or regional dialects may be linked to a place name or a geographical element.
In French, the particle "De-" usually means "of" or "of", indicating origin or belonging, while "-caux" could derive from a place name or a descriptive term. The root "caux" is not common in modern French, but in ancient dialects or historical records, it may be related to terms describing features of the terrain or a settlement.
From an etymological perspective, the surname Decaux could be interpreted as "de Caux", referring to the region of La Caux in Normandy, France, or a place with a similar name. The La Caux region of Normandy is known for its history and its influence on French toponymy. The presence of the prefix "De-" reinforces the hypothesis that the surname is toponymic, indicating that the first bearers probably came from that area or from a region with a similar name.
As for its classification, the surname Decaux would be mostly toponymic, since it seems to derive from a place or a geographical feature. The structure of the surname does not suggest a patronymic, occupational or descriptive, although in some cases, toponymic surnames may also acquire descriptive connotations if the place of origin had some distinctive characteristic.
History and Expansion of the Surname
The probable origin of the surname Decaux in the Normandy region or in nearby areas of France can be placed in the Middle Ages, when the formation of toponymic surnames was common in Europe. The use of the prefix "De-" indicates that the first bearers of the surname were probably people linked to a specific place, perhaps nobles, peasants or merchants who identified their lineage or origin from their territory of origin.
The expansion of the surname in France and its presence in Belgium and Switzerland may be related to internal migratory movements, wars, or marriages between families from different regions. European colonization and migration, especially in the 18th and 19th centuries, led many French and Belgians to emigrate to America, where the surname settled in countries such as Argentina, the United States, Canada and others, explaining its presence in these regions.
In Latin America, the presence of the surname may be linked to Spanish and French colonization, as well as subsequent migrations. The dispersion in countries such as Argentina, with 31 incidents, and in the United States, with 30, reflects migratory movements that occurred in search of better economic conditions or for political reasons. The distribution in English-speaking countries, such as the United States and Canada, may also be due to the European diaspora and the integration of French and Belgian immigrants into those societies.
In Europe, in addition to France, the presence in Belgium, with 136 incidents, reinforces the hypothesis of an origin in the Franco-Belgian region. The presence in Switzerland, althoughminor, it may also be related to geographical proximity and internal migrations in the Alpine region.
