Abstract
The 2023/24 Kenya Housing Survey (2023/24 KHS) provides a comprehensive analysis of housing conditions, affordability and tenure across the country. The survey was conducted by the Kenya National Bureau of Statistics (KNBS) in collaboration with the State Department for Housing and Urban Development, the State Department for Labour and Skills Development, the Kenya Space Agency, the Directorate of Resource Survey and Remote Sensing and the Central Bank of Kenya. The primary objective of the 2023/24 KHS was to provide up-to-date housing statistics to facilitate evidence-based planning and decision making in the housing sector. In addition, the survey addressed housing challenges in line with national development goals and international commitments such as the Sustainable Development Goals (SDGs). Data collection was carried out from 7th March to 10th May 2024 in all the 47 counties and targeted both households and institutions.
The survey collected data on various aspects of housing, including the stock of dwellings, household spending on housing, land and dwelling ownership, access to utilities, housing affordability, overcrowding, durability of construction materials, and economic and financial statistics related to housing. Additionally, it collected information on the age, size, and characteristics of dwellings. Satellite imagery analysis was also used to assess changes in built-up areas and green spaces in Nairobi City, Mombasa, Kisumu, and Nakuru counties. Different players in the housing sector including tenants and home owners, Housing Financiers, Developers, Water Service Providers, Built Environment Professionals and Housing Regulators (County Government Physical Planning Department, Lands Department and National Environmental Management Authority) were interviewed.

SURVEY DESIGN
The survey employed a cross-sectional study design to collect data for estimating housing indicators at national, rural, urban and county levels. To achieve this, a hybrid data collection system was incorporated, targeting both households and institutions. The household component of the survey was designed independently from that of the institutions. A sample survey was conducted for the households, while a census was carried out for all identified institutions key in the housing sector.

SCOPE AND TARGET POPULATION
The survey covered all 47 counties to ensure that the coverage was comprehensive and representative of the entire country. The household component targeted residential housing units in both urban and rural areas while the institutional component targeted housing developers, real estate firms, Water Service Providers, County Governments-Physical Planning Departments, NEMA and Land Administration Department. The professional component targeted members from Engineers Board of Kenya (EBK), Kenya Institute of Planners (KIPs) and Board of Registration of Architects and Quantity Surveyors (BORAQS).

DATA QUALITY
The quality of data for the Housing Survey was ensured through a multi-step approach. This began with defining the survey's content and scope, designing survey instruments, conducting a pre-test and pilot survey, training survey personnel, and incorporating technology for data collection and transmission. Additionally, data validation, analysis, creation of final report tables, and stakeholder engagement were all integral parts of the process. A thorough process was undertaken to review and refine the survey instruments aimed at eliminating redundancies and ensuring the questions were accurate and relevant to the current housing development programs and addressed user needs. The data collection tools were integrated into CAPI with in-built checks and controls to ensure consistency and flag out any outliers in the data.
A multilevel supervision of the data collection exercise also ensured that the probability of any errors going unnoticed was minimized significantly. To further support the data quality assurance, a dashboard based at the headquarters was also used to monitor the data as fieldwork continued. Upon completion of the data collection, edit specifications were developed by subject matter specialists to provide a basis for cleaning and editing of the data. The specifications were subsequently coded into programs using statistical applications and subjected on the raw data to derive a cleaned dataset that developed the tables in the report.

Sampling

Sampling Procedure
SAMPLE SIZE DETERMINATION
The sample size for the household component of the survey was computed independently for each county. By incorporating the county-specific response rates obtained from previous surveys that used the same household sampling frame, the application of the formula resulted in a sample size of 25,900 households and 1,295 clusters which were randomly selected for the survey.

SAMPLING FRAME
The sample for the household component of the survey was drawn from the Kenya Household Master Sample Frame (K-HMSF), which was developed based on the 2019 Kenya Population and Housing Census. The clusters in K-HMSF were selected using Probability Proportional to Size (PPS) systematic sampling method from approximately 128,000 Enumeration Areas (EAs).
The 47 counties were stratified into 92 sampling strata, comprising urban and rural strata in 45 counties, and purely urban strata for Nairobi City and Mombasa counties. Additionally, the K-HMSF is divided into four components, denoted as C1, C2, C3, and C4. Each component consists of 2,500 clusters, which can serve as independent sampling frames. Depending on the required sample size, any two or more components can be combined to provide a sufficiently large sampling frame.
The institutional component of the survey was conducted using multiple lists obtained from various sources, including the State Department for Housing and Urban Development and Water Service Regulatory Board. The Built Environment Professionals (BEPs) list was sourced from Engineers Board of Kenya (EBK), Kenya Institute of Planners (KIPs) and Board of Registration of Architects and Quantity Surveyors (BORAQS).

SAMPLE SELECTION
A two-stage cluster sampling methodology was adopted for the household component of the survey. In the first stage, clusters were randomly selected from the sampling frame. In the second stage, households within these clusters were selected for interviews. For the institutional component of the survey, a census was undertaken for all Developers, Water Service Providers, Real Estate firms and Built Environment Professionals.

SAMPLING OF CLUSTERS
The clusters in the K-HMSF served as the Primary Sampling Units (PSUs) for the survey, and were independently selected from each of the 92 sampling strata in the frame. The clusters were selected using Equal Probability Selection Method (EPSM) given that enumeration areas that formed the clusters had been selected with Probability Proportional to Size (PPS) and standardization of the clusters undertaken through segmentation of clusters that exceeded the measure of size.

SAMPLING OF HOUSEHOLDS
A fixed number of 20 households were systematically sampled with a random start from the list of households enumerated in each of the selected clusters. Sampling of the households was done centrally at the head office, and interviews were conducted exclusively in the pre-selected households. There was no replacement of clusters or households during the fieldwork.
Weighting
COMPUTATION OF SURVEY WEIGHTS
Given that the household sample was disproportionately allocated to the various sampling strata, the data was not self-weighting, which necessitated the application of survey weights to ensure representativeness of the target population. The survey weights also ensured the data conformed to known population distributions and adjusted for non-response of some of the sampled households effectively minimizing survey non-response bias
The survey weights (W) were computed by taking the inverse of the product of the selection probabilities at each stage of sampling.
