Context
What Is the Gross County Product?
The Gross County Product (GCP) is a geographic disaggregation of Kenya’s national GDP,
estimating the monetary value of goods and services produced within each of the 47 counties in a given year.
Compiled by KNBS in accordance with the 2008 System of National Accounts, it is the primary tool for tracking
county-level economic performance under Kenya’s devolution framework.
“GCP is essential for supporting planning, resource allocation, and monitoring of economic performance at the county level.
It highlights differences in economic activity across counties and presents critical information that guides the preparation
of County Integrated Development Plans.”

Economic Size
Nairobi Still Dominates, But the Gap Is Narrowing
Kenya’s county economies are strikingly unequal in size. In 2024, Nairobi City County alone
accounted for nearly 30% of total national GCP, an economy roughly three times larger than
the next biggest county, Kiambu. The top five counties collectively generate more than half the country’s output.
Top 15 Counties by GCP at Constant 2016 Prices, 2024 (KSh Million)
Nairobi City County remains in a class of its own, posting a real GCP of
KSh 2.998 trillion in 2024. That is driven by a highly diversified economy spanning
financial services, real estate, manufacturing, wholesale & retail trade, and ICT.
It accounted for 37.6% of total services GVA and 36.4% of manufacturing GVA nationally.
30%
Nairobi share of national GCP
Kiambu, Nakuru, Mombasa, and Machakos form a distant but important second tier.
Kiambu benefits from its proximity to Nairobi and a robust agricultural base (tea, coffee, horticulture);
Nakuru is home to major electricity generation facilities; Mombasa drives port logistics and tourism.
Together, the top 5 counties account for roughly 52% of national GCP.

Growth Rates
Which Counties Are Growing Fastest
Absolute economic size is one story, and growth rate is another. Twenty-one of Kenya’s 47 counties
expanded faster than the national average of 4.5% per year over 2020–2024, with some frontier
and semi-arid counties recording exceptional spurts from a low base.

“On average, twenty-one county economies registered higher GCP growth than the national growth rate (4.5%)
during the 5-year period. The top five counties in terms of economic growth were Tana River (8.4%),
Isiolo (7.9%), Mandera (6.6%), Kajiado (6.2%) and Nairobi City (5.7%).”
KNBS GCP Report 2025, Part 4
The fastest-growing counties are largely frontier and semi-arid counties such as Tana River, Isiolo,
Mandera, and Kajiado, growing from a lower economic base. This reflects increased government
investment, infrastructure expansion, and the onset of extractive industries (petroleum exploration in Turkana,
soda ash in Kajiado, titanium in Kwale).

Isiolo avg. growth 2020–2024
Agricultural counties, particularly Elgeyo/Marakwet (0.4%), Nyandarua (1.3%) and
Meru (3.8%), recorded below-average growth, reflecting the drag of weather variability
and volatile commodity markets. The report notes: counties with more diversified economic structures
experienced relatively faster growth.

Wealth Distribution
Where Economic Wellbeing Is Highest
Dividing total county GCP by population gives a per-capita measure, a proxy for average economic wellbeing.
In 2024, Kenya’s nominal GDP per capita stood at KSh 309,460, but only seven counties
exceeded this threshold, revealing deep regional inequalities.

Wide gap vs. KSh 309K national average
Nairobi City leads with a per-capita GCP of KSh 850,332, nearly
three times the national average, despite being the most populous county. This is driven by its
highly diversified economy: manufacturing, financial services, real estate, distributive trade, and ICT.
Mombasa follows at KSh 530,747, boosted by port logistics and tourism.

At the other end of the spectrum, Wajir (KSh 85,600), Mandera (KSh 89,903)
and Garissa (KSh 93,965) record the lowest per-capita GCP, less than one-tenth
of Nairobi’s. These counties face structural barriers: sparse populations over vast arid land,
high infrastructure costs, and limited access to markets.

Sectoral Analysis
What Drives Each County’s Economy?
Kenya’s county economies are powered by four broad sectors: Agriculture, Manufacturing,
Other Industry & Construction, and Services. Each county’s economic character is shaped by
which sectors dominate, and the divergence between agricultural and urban counties is stark.
Agriculture, Forestry & Fishing~21.8%
Manufacturing~9.8%
Other Industry & Construction~7.5%
Services (all other)~60.9%

5-yr average (2020–2024), % of national agricultural GVA
Top 8 Counties: Manufacturing GVA Share
5-yr average (2020–2024), % of national manufacturing GVA
Agriculture remains Kenya’s most distributed sector, with Meru (8.1%)
and Nakuru (6.4%) leading national contributions. Other strong agricultural counties
include Nyandarua, Murang’a, Kiambu, Bungoma, Nandi and Kakamega, all benefiting from diverse
soil types and reliable rainfall.
8.1%
Meru’s share of national agri. GVA
Manufacturing is far more concentrated. Nairobi City alone commands
36.4% of the national manufacturing GVA, followed by Mombasa (9.8%), Kiambu (8.3%) and Machakos (8.0%).
ASAL counties like Wajir, West Pokot, Tana River, Marsabit, and Isiolo each contribute only 0.1%.
36.4%
Nairobi share of national mfg. GVA
In Services, Nairobi City leads with 37.6% of national services GVA, followed by
Mombasa (5.6%), Kiambu (4.9%), Nakuru (4.3%), Uasin Gishu (2.6%) and Kisumu (2.6%).
These are counties with thriving urban settings where financial services, trade, ICT and public
administration concentrate.

Regional Profiles
Five Economic Zones, Five Different Stories
While counties are the unit of measurement, regional patterns tell a powerful story about structural
inequalities between the urban coast and interior, and the fertile highlands and the arid north.
What the Data Tells Us About Kenya’s County Economies
The 2025 GCP report paints a picture of a country in transition, where devolution has given counties
the mandate but not always the resources to develop at equal pace.
Concentration
Economic power still highly concentrated
5 counties produce 52% of national GCP; Nairobi alone contributes 30%.
Convergence
ASAL counties are growing fastest
Tana River, Isiolo and Mandera outpace the national average, a hopeful sign.
Agriculture
A stable but vulnerable foundation
Agriculture’s ~22% GDP share is consistent but weather-sensitive counties lag.
10:1 Gap
Per-capita inequality persists
Nairobi’s KSh 850K vs Wajir’s KSh 86K, a tenfold gap demanding policy attention.
Diversification
The key to faster growth
Counties with mixed economies (services, manufacturing and agriculture together) consistently outperform.
