Population Projection of Nepal: Policy and Socio-Economic Implications

The population dynamics of Nepal are undergoing a significant transition, moving from high growth to a phase of slow growth and subsequent aging. Understanding these projections is crucial for national planning and achieving sustainable development goals.

6.1 Definition of Population Projection and Estimates

Population Estimates

Population estimates refer to the calculation of the population size and characteristics for a past or present date where a full census count is unavailable. They are typically based on the most recent census data and are updated by accounting for the three demographic components since the census date: births, deaths, and net migration (immigration minus emigration).

Population Projection

A population projection is an estimate of the future size and structure (by age and sex) of a population. Unlike an estimate, a projection is a conditional statement—it illustrates what the population would look like if the stated assumptions about future fertility, mortality, and migration rates hold true.

• Conditional Nature: Projections are not forecasts, which aim to predict the most likely future outcome. Instead, they provide “if-then” scenarios.
• Methodology: The most common method is the Cohort-Component Method (CCM), which separately projects the components (fertility, mortality, migration) for each age and sex cohort over time.
• Assumptions: Multiple scenarios (e.g., High, Medium, Low) are often created by varying the key assumptions, particularly the Total Fertility Rate (TFR) and Net Migration Rate, as they are the most volatile and influential factors.

6.2 Sectoral Projection of Population (Size, Growth Rate/Decline, Structure)

Nepal’s population is experiencing a noticeable demographic shift driven by a rapid decline in fertility and continued international migration.

A. Population Size and Growth Rate/Decline

Nepal’s population size is projected to continue growing, but the annual growth rate is slowing down and is expected to eventually turn negative in the long term, leading to an overall population decline.

The peak population is projected to occur around the mid-2040s (e.g., 2043 at $33.5$ million), after which the size is expected to start decreasing due to sub-replacement fertility and sustained emigration.

B. Population Structure (Age-Sex Structure and Urban-Rural)

The most impactful change is the shift in the age-sex structure, which can be visualized by the narrowing base and widening middle and top of the population pyramid:

• Age Structure Transition:
  • Child Population (0-14 years): The proportion of this age group is decreasing significantly due to the declining TFR.
  • Working-Age Population (15-59/64 years): This group currently forms a large proportion (the “youth bulge” or demographic dividend window) and is projected to peak around the 2050s. For example, the working-age population is projected to peak at around $69.4\%$ in 2051.
  • Elderly Population (60+ years): This proportion is rapidly increasing. The share of the elderly population (60+) has increased from $7.6\%$ in 2011 to $9.0\%$ in 2021 and is projected to continue growing, signaling the onset of an aging population.
• Urban-Rural Dynamics:
  • Urbanization is a key trend, with an increasing proportion of the population residing in urban areas. This is driven by internal migration from rural to urban centers, creating dense urban clusters.
  • Conversely, many rural areas are experiencing a rise in “empty households” as young, working-age individuals migrate internationally or domestically to urban centers, leaving behind a disproportionate share of children and the elderly.

6.3 Socio-Economic Implications of Future Projected Population

The projected demographic shifts have profound implications for Nepal’s socio-economic development and the quality of life of its citizens.

A. Demographic Dividend and Economic Growth

The large, peaking working-age population (15-59/64) presents Nepal with a window of opportunity known as the demographic dividend.

• Opportunity: A high proportion of working-age individuals relative to dependents (children and elderly) means a lower dependency ratio. This can spur economic growth through increased labor supply, higher savings rates, and greater productivity.
• Condition for Success: The dividend is not automatic. It requires strategic investment in:
  • Education and Skills: Equipping the youth bulge with relevant skills for the modern economy.
  • Job Creation: Ensuring sufficient formal and productive employment opportunities.
  • Health: Maintaining the health and well-being of the workforce.
• Risk: Failure to capitalize on this window—due to a lack of quality employment and high emigration—means the opportunity will pass, and the burden of supporting a rapidly aging population will begin to rise.

B. Quality of Life and Social Services

The changing structure places differentiated demands on social services:

• Health and Healthcare: The aging population will necessitate a shift in the healthcare system’s focus towards geriatric care, non-communicable diseases (NCDs), and long-term care facilities, requiring increased public expenditure and specialized medical personnel.
• Education: The declining child population (0-14) will eventually lead to lower enrollment demands at the primary level. This presents an opportunity to focus resources on improving the quality of education and skills development, particularly for the large youth cohort.
• Migration and Remittances: High rates of international migration, while contributing to the negative net migration rate, are also the primary source of remittances. These remittances are a major pillar of Nepal’s economy, boosting consumption and reducing poverty. However, this reliance creates vulnerabilities (e.g., global economic shocks) and has social costs, such as the disintegration of family units and mental health challenges for those left behind.

C. Resource Management and Infrastructure

The trend of rapid urbanization intensifies pressure on core infrastructure and resources:

• Urban Planning: Cities face challenges in providing adequate housing, transport, sanitation, and utilities (water, energy) for the growing urban population. Unplanned urban sprawl can lead to environmental degradation and resource strain.
• Environmental Pressure: The Malthusian theory suggests that rapid population growth, especially concentrated in specific areas, can lead to increased pressure on natural resources, including agricultural land, forests, and water bodies, potentially exacerbating issues like landslides and water scarcity.
• Fiscal and Budgetary Implications: The government will need to manage budgetary trade-offs. On one hand, maintaining a healthy, educated workforce requires significant investment (education, health, infrastructure). On the other, the growing elderly population will require increasing consumption-based expenditure (social security, pensions, old-age allowances), which could strain public finances.

The projected population trends in Nepal highlight a critical period where proactive, integrated policy planning across economic, social, and environmental sectors is essential to convert the potential demographic dividend into tangible and sustainable national development gains.
