The province's topography consists of hilly regions in the west (70%) and the fertile plain of Tuy Hòa in the east. Lowlands also extend west alongĐà Rằng River.[5] The highest peaks are at 1,592 m on the border ofKhánh Hòa province in the south and at 1,331 m in the northwest (Đồng Xuân District).[6] There are several hills near the coast, including Mô Cheo (Núi Mô Cheo, 814 m) inSông Cầu and Đá Bia (Núi Đá Bia, 706 m) nearĐại Lãnh inĐông Hòa District.[6]
The main rivers that flow across Phú Yên are theĐà Rằng River (the largest river in Central Vietnam),Bàn Thạch River andKỳ Lộ River. Sông Hinh Lake, a large artificial lake, is located in the southwest of the province.[5]

As of 2007 Phú Yên has a population of 880,700. It has a relatively small urban population (178,600), making up 20% of the province's population. With 174 people per square kilometer, it is also one of the least densely populated provinces of the South Central Coast.[7] Population density is relatively high (exceeding 500/km2) along the lowerĐà Rằng River, but is lower than 50/km2 in much of the western part of the province.[5] Average yearly population growth between 2000 and 2007 has been 1.3%, close to the regional average.[8] Urban population growth has been faster with 2.2% per year on average.[8]
With aGDP per capita of 8.43 millionVND[8] in 2007 and a relatively small industrial sector, Phú Yên is one of the less developed provinces of theSouth Central Coast.
Phú Yên has had a trade deficit. In 2007, it exported goods worth US$72.7 million while importing goods worth US$116.25 million, mainly fuel, raw materials, machinery, and medical goods.[7]
Total employment was at 482,800 in 2007. The vast majority (361,400) are still employed in agriculture, forestry, and fishing. 45,600 people were employed in industry and construction and 75,800 in the service sector. Both industry and service have shown little employment growth between 2005 and 2007. Service employment has actually declined significantly since 2000.[7]
The main agricultural regions of the province are the plains aroundTuy Hòa and the lowlands along theĐà Rằng River.[5] In 2007 the rice harvest was 321,800 t.[7] It is the South Central Coast's largest producer of sugar-cane with a harvest of 1.051 million t (6% of Vietnam's total harvest). Cultivation of cotton and tobacco is also significant, with 800 t (5% of the national total) and 700 t (2.2%) respectively.[8] Other crops include peanuts, cashew nuts, pepper, and coffee.[7]
Phú Yên has a relatively large fishing sector. Itsgross output is the third largest in the South Central Coast afterKhánh Hòa province andBình Định province.[7] Aquaculture, mostly shrimp farms, make up around one third of the fishing output, while using 2300 ha.[7]
Phú Yên is one of the less industrialized provinces of the South Central Coast. Its industrial production is mostly based on the processing of local primary products such as fish, shrimp, cashew nuts and sugar. The province also produces mineral water, beer, garments, and cement.[7] Industrial parks are located in the north ofTuy Hòa andSông Cầu, nearQui Nhơn.[5]
The province is zoning and developing a large economic zone, namely theNam Phú Yên Economic Zone in southernĐông Hòa District.[5] Upon completion, it will become an oil-refining hub in Vietnam and potentially provide high profits for the province.[citation needed]
A hydropower plant is located inSông Hinh District in the southwest of Phú Yên.[5] It is built on theHinh River, a major tributary of theĐà Rằng River and which created a lake of the same name (Sông Hinh Lake, meaning River Hinh Lake). Phú Yên produced 379.9 million kWh of electricity in 2007.[7]
