and making homeownership unattainable for most residents (Mulugeta & Worku, 2020). Informal settlements
have expanded as low-income households seek substandard housing alternatives, while the limited availability
of serviced land, high infrastructure costs, and bureaucratic constraints hinder affordable housing development
(Addis Ababa Urban Planning Bureau, 2019). Applying the Median Multiple in this context provides a
quantitative lens to assess affordability levels, identify vulnerable groups, and evaluate the effectiveness of
current housing policies.
The literature indicates that housing affordability is a multi-dimensional challenge shaped by demographic,
economic, and policy factors. While global and African studies provide benchmarks for affordability, Ethiopia
and Addis Ababa face unique constraints due to rapid urbanization, limited formal housing supply, and
socioeconomic disparities. The Median Multiple serves as a valuable tool for quantifying affordability gaps,
guiding policy interventions, and informing sustainable urban planning. This study builds on these insights to
analyze housing affordability in Addis Ababa, highlighting socio-economic drivers, market constraints, and
policy implications.
Concept of Housing Affordability
Globally, housing affordability is broadly defined as the ability of households to access adequate housing
without incurring a disproportionate financial burden. A widely recognized benchmark suggests that
households should spend no more than 30% of their gross income on housing costs, including rent or mortgage
payments, utilities, and other essential expenses (Stone, 2006; UN-Habitat, 2020). Affordability is not only
about cost—it also encompasses access to suitable housing in terms of quality, location, and availability of
essential services. In rapidly urbanizing cities worldwide, rising population growth, land scarcity, and
escalating construction costs have intensified affordability challenges, particularly for low- and middle-income
households. Housing unaffordability often contributes to overcrowding, informal settlements, and
socioeconomic inequalities (Angel et al., 2012; UN-Habitat, 2016).
Housing affordability is typically measured in terms of disposable income, with affordable housing defined as
costing no more than five times a household’s gross annual income. For renters, housing costs should not
exceed 30% of gross monthly income (Elshadai Baja, 2017). According to the U.S. Department of Housing
and Urban Development (HUD), households spending more than 30% of income on housing are considered
cost-burdened, and evaluating the true cost of housing must account for related expenses such as water,
electricity, and gas, which are essential for a healthy and livable home.
In the African context, housing affordability faces similar pressures but is further complicated by systemic
challenges such as informal land markets, limited mortgage financing, and weak regulatory frameworks. Many
African cities experience severe housing shortages, forcing a significant proportion of urban residents into
informal settlements (Huchzermeyer, 2009; UN-Habitat, 2014). Studies indicate that in Sub-Saharan Africa,
most households spend well above the recommended 30% of income on housing, reflecting both market
failures and inadequate public housing provision. Informal and substandard housing is widespread, with
limited access to essential services such as water, sanitation, and electricity (UN-Habitat, 2014).
In Ethiopia, housing affordability has emerged as a major urban development concern, particularly in rapidly
growing cities. The housing market is characterized by limited formal housing supply, high land and
construction costs, and inadequate access to housing finance, disproportionately affecting low- and middle
income households (Mulugeta & Worku, 2020; Gebre & Singh, 2022). Government initiatives, such as the
Integrated Housing Development Program (IHDP), aim to expand affordable housing, but evidence suggests
that these programs often benefit middle- and upper-income groups more than low-income households (Larsen
& Yeshitela, 2021). Consequently, many urban residents either allocate an excessive share of their income to
housing or live in informal and substandard units (Alemayehu & Assefa, 2019).
Addis Ababa, as Ethiopia’s capital and largest city, exemplifies these affordability challenges. Rapid
population growth, exceeding 4% annually, coupled with rural-urban migration, has created a severe mismatch
