This migration is driven by poverty, lack of employment, and limited access to basic services such as healthcare and education. As a result, informal settlements are becoming a major challenge for the government and local authorities. Unregulated growth in informal settlements poses significant risks to public health, safety, and infrastructure. Unplanned development can lead to overcrowding, inadequate sanitation, and poor waste management. As cities expand rapidly, the need for effective urban planning is critical. However, the lack of reliable population data hinders the government’s ability to develop strategies that address the root causes of urbanization, such as poverty and lack of access to basic services. The current census methodology used by the Papua New Guinea government is a traditional face-to-face survey, relying on manual data collection. This approach is time-consuming, labor-intensive, and prone to errors. The lack of technology and resources hinders the ability to collect accurate data. The 2011 census, for example, was criticized for undercounting the population, with estimates suggesting that the actual population may have been as much as 20% higher than reported. The 2019 census was also criticized for its methodology, with many respondents claiming that the survey was not representative of the population. The 2019 census was conducted in a single week, which may not have captured the full scope of urbanization and migration. The government has proposed a new census methodology that would use a combination of traditional face-to-face surveys and administrative data, such as utility bills and tax records.

Understanding the Challenges of Census Data

The 2011 census, conducted in India, faced numerous challenges that impacted its accuracy and reliability. One of the primary concerns was the lack of adequate infrastructure, particularly in rural areas. Many villages lacked basic amenities such as roads, electricity, and communication networks, making it difficult for census officials to reach and collect data from these areas. • The lack of infrastructure hindered the census team’s ability to conduct door-to-door surveys, which are essential for collecting accurate data. • Inadequate training and resources also contributed to the challenges faced by census officials.

The Challenges of Estimating Population in Rural PNG

Estimating population in rural areas of Papua New Guinea (PNG) is a complex task due to the lack of infrastructure and limited access to data. The United Nations Population Fund (UNFPA) has been using a technique called satellite imagery analysis to estimate the population in rural areas.

The lack of reliable population data hampers the ability of the 2019 Papua New Guinea Census to provide meaningful insights into the country’s population dynamics.

Logistical and Administrative Constraints

Logistical and administrative constraints reduced the standard comprehensive questionnaire to just six basic identification questions. The 2019 Papua New Guinea Census faced significant logistical and administrative challenges in collecting population data.

However, the lack of infrastructure and inadequate planning are more significant factors.The Mt Erima Treatment Plant: A Case of Inadequate Infrastructure

The Mt Erima treatment plant, located in the heart of Papua New Guinea, is a prime example of the consequences of inadequate infrastructure and poor planning.

The Challenges of Informal Settlements

Informal settlements pose significant challenges for the government and the residents themselves.

The Challenges of Settlement Development

Infrastructure and Planning

Infrastructure development can have a profound impact on settlements, often leading to displacement and marginalization of existing residents. In many cases, infrastructure projects are designed with the intention of modernizing and improving living conditions, but they can also displace communities and disrupt social networks. For instance, the construction of roads, highways, and public transportation systems can lead to the destruction of homes and businesses, forcing residents to relocate to new areas. • The lack of consideration for existing residents and their needs can exacerbate social and economic inequalities. • Infrastructure development can also lead to the loss of traditional livelihoods and cultural practices.

The city of Port Moresby, the capital of Papua New Guinea, is a rapidly growing urban center with a population of over 300,000 people.
