Collecting Population Data in Developed and Developing Countries

Counting the heads

Accurate population data is a fundamental resource for governments worldwide, whether in developed or developing countries. It provides essential insights into the size, distribution, and characteristics of populations, enabling informed decision-making and effective planning across multiple sectors.

The census isn’t a recent innovation; many countries have attempted to count their population, often for tax-raising purposes. The earliest known census was in 3800 BCE in the Babylonian Empire; it counted livestock and quantities of butter, honey, milk, wool, and vegetables.

Long before modern demographic studies, imperial China pioneered a sophisticated system of population registration—not for social welfare, but for fiscal control. The roots of these surveys trace back to the Warring States period (475–221 BCE), when philosopher Guan Zhong advocated “registering the people to secure the state’s wealth.” By the Han Dynasty (206 BCE–220 CE), the “Bamboo Annals” recorded early attempts at household registration, laying the groundwork for what would become a cornerstone of imperial governance.

In 2 CE, the first census of which records are preserved was taken in China during the Han Dynasty. At that time, there were 57.5 million people living in Han China the world’s largest nation by population and a considerable administrative undertaking.

The Sui Dynasty’s (581–618 CE) explosive population growth—from 4 million to 8.9 million households within two decades—wasn’t a biological miracle but bureaucratic revelation. Emperor Yang’s infamous 609 CE “Great Scrutiny” campaign exposed how many Chinese had circumvented the census demands and undercounted to avoid tax!

The Census of Quirinius, conducted in 6 CE by the Roman governor of Syria, Publius Sulpicius Quirinius, aimed to establish property taxes in the newly formed Roman province of Judaea and triggered a revolt by Jewish Zealots. Suspicion of the census and the wish to avoid taxation are not new.

The history of census collection in the UK can be traced back to the Domesday Book in 1086, which was ordered by William the Conqueror to establish the ownership of assets for taxation purposes. This event marked the beginning of systematic census-taking in England. The Domesday Book provided a detailed inventory of land and property and is considered the first census in England. However, it did not provide an accurate count of the people living in England at the time.

Since 1801, a census has been conducted in England and Wales every 10 years. This survey gives the government the most accurate picture of the country and is a fascinating reflection through time.

Enumerators on horseback begin the first U.S. census in 1790, which took 18 months to complete. The results were used to establish the size of the House of Representatives. Enslaved people were counted as three-fifths of a person until after the Civil War (1861-1865), and Native Americans weren’t counted at all until 1860.

Why Accurate Population Data Matters

For Developed Countries

• Policy and Service Planning: Governments need precise data on population size, age structure, and geographic distribution to plan health services, education, housing, and transportation effectively.
• Economic Development: Understanding labour market trends and demographic shifts helps tailor economic policies and workforce training programs.
• Social Services and Infrastructure: Accurate data supports the allocation of resources for social welfare, public safety, and infrastructure development.
• Migration and Urban Planning: Population and migration statistics guide urban development and integration policies.
• Public Debate and Governance: Reliable data underpins transparent governance and informed public discourse.

For Developing Countries

• Development Planning: Population data is critical for designing policies that address education, healthcare, poverty reduction, and infrastructure needs.
• Sustainable Development Goals (SDGs): Reliable demographic data is essential to monitor progress towards SDGs and to implement targeted interventions.
• Humanitarian Response: Data on population dynamics aids in disaster management, migration, and emergency response planning.
• Environmental Management: Understanding population density and distribution helps in managing natural resources and mitigating environmental degradation.
• Economic Growth: Data informs investment decisions and helps tailor economic development strategies to demographic realities.

Challenges in Collecting Population Data

Accurate census data is vital for effective governance and development planning. However, in many developing countries, a range of social and political challenges undermine the reliability of census results.

Social Challenges

• High Illiteracy Rates: Many people in developing countries have limited education, making it difficult for them to understand the purpose of the census or accurately complete forms. This can lead to underreporting, misreporting, or refusal to participate.

• Traditional and Religious Beliefs: In some communities, cultural or religious beliefs discourage participation in censuses. For example, some people believe that counting individuals is taboo or fear that census data will be used for taxation or conscription.
• Distrust of Government: A lack of trust in government institutions can make people reluctant to provide personal information, fearing misuse or negative consequences.
• Language Barriers: Multilingual societies may struggle with census forms that are not available in all local languages, leading to confusion and errors.
• Nomadic and Hard-to-Reach Populations: Nomadic groups and people living in remote or inaccessible areas are often missed, resulting in undercounting.
• Insufficient Public Awareness: Weak or ineffective educational campaigns about the importance of the census can reduce participation and cooperation.
• Fragile and Conflict-Affected Areas: Violence, displacement, and hostility towards government officials make data collection dangerous and difficult.
• Cost and Resource Constraints: Conducting comprehensive censuses is expensive and often beyond the financial capacity of many developing countries.

Political Challenges

• Political Interference and Manipulation: Census data often influence the allocation of political power and resources. This can lead to deliberate manipulation, such as inflating or deflating population figures to benefit certain regions or groups.
• Ethnic and Religious Rivalries: In countries with significant ethnic or religious divisions, groups may attempt to influence census outcomes to gain political advantage, leading to disputes and mistrust of the results.
• Falsification of Data: There are instances where census officials or local leaders intentionally falsify data, either to increase their own group’s numbers or to disadvantage rivals.
• Recruitment and Training Issues: Political favouritism in hiring census workers can result in unqualified personnel, reducing the quality and reliability of data collection.
• Security Concerns and Conflict: In areas affected by conflict or political instability, census operations may be disrupted or rendered impossible, leading to incomplete or inaccurate data.
• Public Distrust Due to Political Climate: Political crises or institutional instability can erode public confidence in the census process, further reducing participation rates

Other constraints

• Fragile and Conflict-Affected Areas: Violence, displacement, and hostility towards government officials make data collection dangerous and difficult.
• Cost and Resource Constraints: Conducting comprehensive censuses is expensive and often beyond the financial capacity of many developing countries.

Comparisons with Developed Countries

• Developed countries generally have well-established civil registration systems that continuously record vital events such as births and deaths.
• They benefit from advanced infrastructure, higher literacy rates, and more stable political environments, facilitating more accurate and timely data collection.
• Census-taking is often supplemented by administrative data and large-scale surveys, improving data quality and reducing costs.
• In contrast, many developing countries rely heavily on periodic censuses and sample surveys due to the absence of continuous registration systems.

Accurate population data is indispensable for both developed and developing countries to plan effectively, allocate resources wisely, and promote sustainable development. While developed countries face fewer obstacles in data collection due to better infrastructure and systems, developing countries encounter significant challenges that require targeted support and innovative solutions to overcome.
