National income measurement is fundamental for human resource professionals, as it reflects the overall economic health and productivity of a country, influencing employment, wages, and labour market conditions. In Kenya, understanding national income figures enables HR managers to align workforce planning, compensation strategies, and training programs with economic realities. This chapter explores key concepts of national income, providing HR practitioners with a foundation to interpret economic data critically and apply it in organisational decision-making.
National income represents the total value of goods and services produced by a country's economy over a specific period, usually one year. It serves as a broad indicator of economic performance and living standards, which directly affect labour demand and wage levels. For HR professionals in Kenya, grasping the nuances of national income components such as GDP, GNP, and disposable income is crucial for forecasting labour market trends and advising on human capital investments.
Gross Domestic Product (GDP) is the total market value of all final goods and services produced within a country’s borders during a given period, typically one year. It excludes the value of intermediate goods to avoid double counting and focuses solely on final output.
GDP quantifies economic activity confined geographically within Kenya, regardless of whether the production is carried out by Kenyan nationals or foreign entities. This measure is essential for assessing domestic economic growth and the capacity of the economy to generate employment opportunities.
GDP can be calculated using three approaches, each providing a different perspective on the economy:
GDP growth signals expanding economic activity, often leading to increased demand for labour and better job prospects. HR managers at institutions like the Nairobi County government monitor GDP trends to anticipate recruitment needs and adjust workforce development strategies accordingly.
GDP does not account for income distribution disparities, informal sector activities prevalent in Kenya, or non-market transactions such as subsistence farming. These gaps mean HR professionals must supplement GDP data with other labour market indicators for comprehensive workforce planning.
While GDP focuses on production within territorial boundaries, Gross National Product (GNP) extends the scope to include production by Kenyan residents regardless of location, subtracting foreign production within Kenya.
GNP measures the total market value of all final goods and services produced by the nationals of a country, whether inside or outside the country’s borders. For Kenya, this includes income earned by Kenyans working abroad or Kenyan-owned businesses operating internationally.
GNP is derived by adjusting GDP for net income from abroad:
GNP = GDP + Net Factor Income from Abroad
Net factor income includes wages, dividends, and profits received from foreign investments minus similar payments made to foreign investors within Kenya.
NNP adjusts GNP by subtracting depreciation (capital consumption allowance), the value of worn-out or obsolete capital assets during production.
NNP = GNP − Depreciation
This figure reflects the sustainable level of output that can be maintained without reducing the capital stock, providing HR planners insights on long-term economic health.
Understanding GNP and NNP helps HR teams in multinational companies or those with diaspora employees to evaluate the broader economic contributions of Kenyan nationals. For example, SACCOs with members working abroad may consider remittance flows in their strategic planning.
Net National Income (NNI) represents the total income accruing to a nation’s residents after accounting for depreciation. It can be measured at market prices or factor cost, each providing distinct information relevant to economic analysis.
NNI at market price is the value of all final goods and services produced by nationals minus depreciation, evaluated at prices paid by consumers including indirect taxes and subsidies.
NNI at Market Price = NNP at Market Price − Depreciation
This measure reflects the purchasing power of income generated within the economy.
NNI at factor cost adjusts market prices by removing indirect taxes and adding subsidies, reflecting the actual earnings of factors of production (labour, capital, land).
NNI at Factor Cost = NNI at Market Price − Indirect Taxes + Subsidies
This measure is important for HR professionals assessing wage shares and income distribution among employees.
Market price includes taxes and excludes subsidies, which can distort the real income available to factors of production. Factor cost provides a clearer picture of incomes received by labour and capital, aiding in wage negotiations and compensation policy formulation.
When negotiating collective bargaining agreements at institutions like Kenyatta University, HR managers use NNI at factor cost to benchmark fair wage levels relative to the income generated by employees’ productive efforts.
Disposable income is the amount of money households have available for spending and saving after income taxes have been deducted. It is a critical indicator of consumer purchasing power and living standards.
Disposable income equals personal income minus direct taxes such as PAYE (Pay As You Earn) and other compulsory contributions. It determines the capacity of individuals to consume goods and services or save.
Disposable income is affected by:
Disposable income influences employee morale and productivity, as workers with higher disposable income can meet their needs better. HR departments at retail companies like Nakumatt (now rebranded) analyze disposable income trends to design appropriate employee benefits and incentive schemes.
Higher disposable income typically leads to increased demand for goods and services, stimulating business growth and job creation. County governments in Kenya consider disposable income data when planning employment initiatives to reduce urban poverty.

Key measures include Gross Domestic Product, which captures the output within national borders, Gross National Product and Net National Product that account for international income flows and depreciation respectively, and Net National Income calculated at market prices and factor cost reflecting income earned by factors of production. Disposable income represents the amount available to households after taxes. National income can be measured using three primary methods: the income approach, which sums all incomes earned; the output approach, which totals the value added at each production stage; and the expenditure approach, which aggregates total spending on final goods and services. Challenges in national income measurement arise from factors such as informal economic activities and data collection difficulties. Despite these problems, national income statistics are crucial for economic planning, policy formulation, and assessing economic performance. The concept of national income equilibrium explains the balance between total output and total expenditure in the economy.
