Finding a developed synonym means first asking what grew: an economy, a child, a plan or a gadget. Advanced, mature, detailed, refined and created each match one of those uses.
Developed works as both an adjective (a developed nation) and the past tense of develop (she developed an app). Swapping in another word for developed works differently in each role, so the sections below split them up and flag labels that many writers now prefer in essays about wealth and poverty.

From formed to sophisticated
The chips read from simple to advanced. Formed only says something has taken shape. Grown adds size or age. Mature means it reached its full state. Refined says it has been improved and polished. Sophisticated suggests complexity and skill, as in a sophisticated argument.
Choose the level your evidence supports. A rough draft may be formed, but calling it sophisticated will set your reader up for disappointment.
Developed countries: careful labels
In economics and geography essays, developed country is still common. Alternatives include high-income country, industrialized nation and advanced economy. Many writers prefer income labels because they describe a measurable fact rather than ranking whole societies.
The opposite, developing or low-income country, has the same issue. Older terms like third world now sound dated. For more on this vocabulary, see the society synonyms page.

A resume bullet: "Developed training. Developed onboarding. Developed a help guide." A sharper version: "Designed staff training, built a new onboarding flow and wrote the help guide." Each verb shows the real task.
Well-developed and fully developed
Teachers often write "well-developed" in feedback on essays. It means the paragraph has enough detail and support. Swaps include thorough, well-supported, fleshed out and in-depth.
Fully developed suits living things and finished products: fully grown, full-sized, complete. A detailed plan and a complete plan are not the same, though: detailed is about depth, complete is about nothing missing.
Opposites of developed
Underdeveloped and undeveloped differ. Undeveloped land has no buildings yet, which may be a good thing. Underdeveloped suggests it should have grown more but has not. Immature fits people and fruit. Rudimentary, basic and sketchy fit plans and skills.
- His French is still rudimentary.
