By the Numbers: Nairobi's Migrant Population Is Growing Faster Than the City's Integration Programmes Can Handle

Nairobi is now home to an estimated 740,000 migrants and refugees — a figure that has climbed roughly 18 percent since 2022, according to projections drawn from Kenya National Bureau of Statistics census data and UNHCR urban refugee counts. The city's formal integration infrastructure, stretched thin under the Ruto government's IMF-mandated austerity programme, has not kept pace. Three dedicated urban refugee support centres serve a population the size of a mid-sized Kenyan town.

The timing matters. Kenya's Nairobi Metropolitan Area Vision 2030 delivery secretariat is currently reviewing city-level social cohesion indicators ahead of a September 2026 funding review. How officials characterise the migrant integration gap will directly influence whether budget allocations shift toward community-level programmes or remain locked in the humanitarian pipeline managed from the Gigiri corridor. With the Gen Z tax revolt of 2024 still shaping public appetite for any new government spending, the politics are delicate.

Where People Are, and Where the Services Are Not

The largest concentrations of Nairobi's urban migrant population sit in Eastleigh — sometimes called Little Mogadishu — and in the Pangani and Huruma neighbourhoods further north. A 2025 survey by Heshima Kenya, an organisation operating out of Ngara that focuses specifically on urban refugees and asylum seekers, found that 61 percent of respondents in Eastleigh's Section III had lived in Nairobi for more than five years yet had never accessed a single government-run social service. Language barriers accounted for 34 percent of that gap, according to the same survey. Lack of documentation was cited by 48 percent.

The Mathare Social Justice Centre, based along the Mathare River corridor, has been tracking a parallel story inside informal settlements where Congolese, Ethiopian, and South Sudanese families have settled alongside Nairobi's domestic rural-urban migrants. Their 2025 community mapping exercise counted 23 distinct mother-tongue language groups in a single 400-metre stretch of Muthurwa Market. The centre argues that city planners are still designing integration around a 2010-era model that treats migrants as a temporary caseload rather than a permanent demographic.

What the Data Actually Shows About Economic Participation

Economic integration figures tell a more complicated story than the humanitarian framing suggests. The Kenya Revenue Authority's 2024 annual report noted that informal-sector tax filings — including from Eastleigh's textile and electronics trade, much of it driven by Somali and Ethiopian entrepreneurs — contributed an estimated Ksh 4.2 billion to Nairobi County revenue, up from Ksh 3.1 billion in 2021. That growth happened largely without formal support programmes.

Still, barriers are real and measurable. The average cost for a migrant to legalise a small business through City Hall's Nairobi Business Registration portal stands at Ksh 18,000 in direct fees — before factoring in the informal facilitation payments that fixers along Haile Selassie Avenue routinely charge, which community organisations estimate add another Ksh 8,000 to Ksh 15,000 to the process. For a South Sudanese market trader earning Ksh 600 a day, that is more than a month's net income. The Nairobi Integration and Social Cohesion Programme, a joint City County and IOM initiative launched in March 2024, has processed just 1,200 business facilitation cases in its first 15 months — against a self-stated target of 10,000 by end of 2026.

The programme's offices on Upperhill's Elgeyo Marakwet Road acknowledge the shortfall. Internal documents reviewed by The Daily Nairobi show that only 40 percent of the initiative's Ksh 280 million budget had been disbursed by April 2026, largely because of procurement delays tied to Treasury single-account reforms under the IMF programme.

Advocates say the September funding review is the clearest near-term opportunity for course correction. Heshima Kenya and the Refugee Consortium of Kenya are both scheduled to present evidence to the Nairobi County Assembly's Social Services Committee before August 14. For the families buying vegetables at Kangemi Market or running electronics stalls off Luthuli Avenue, that committee meeting is about as abstract as it gets — but the numbers it will consider are anything but.
