In today's global landscape, demographic shifts have become a pressing concern for many advanced economies, including Aotearoa New Zealand. The recent report by Koi Tū, an independent think tank, calls for a national population strategy to address the country's demographic challenges. While this report offers a compelling case, it is crucial to approach it with a critical eye and consider the broader implications and potential pitfalls.
The Demographic Inflection Point
The notion of an inflection point in demographics is a powerful concept. Demographers have identified several critical thresholds, such as a dependency ratio of two workers per retiree, a fertility rate below 1.5, or a situation where deaths consistently exceed births. Aotearoa is approaching such a moment, with slowing population growth, declining fertility, and an aging population. This is not a new concern; similar issues were raised in a 1986 report, yet little action was taken.
Aotearoa's Demographic Landscape
Compared to many advanced economies, Aotearoa's demographic situation is not in crisis mode. The total fertility rate of 1.55 is above the OECD average, and the population is still growing, with births projected to outnumber deaths for some time. However, trends are concerning, and the lesson from other countries is clear: waiting for a crisis often means acting too late.
The Limits of Policy Intervention
Realism is essential when considering population trends. These trends are influenced by a myriad of factors, such as economic conditions, housing costs, and global migration patterns, which governments can only marginally impact. Fertility rates, in particular, have proven resistant to direct policy intervention, as seen in South Korea's unsuccessful pronatalist incentives. Migration policy offers more leverage, but it comes with significant uncertainty.
Adapting to Inevitable Changes
A credible population strategy must distinguish between what can be shaped and what must be adapted to. The New Zealand Treasury's long-term fiscal statement already models population-related pressures, and a population commission could build on this by focusing on feasible interventions and evidence-based adaptations. This strategy should be tailored to Aotearoa's unique demographic diversity.
Embracing Diversity as a Design Principle
Any population strategy for Aotearoa must prioritize diversity from the outset. The median age difference between Māori (26.8 years) and Pākehā/Europeans (41.7 years) is not just a statistical variation but a reflection of distinct demographic histories and trajectories. Māori and Pacific communities will play a crucial role in supporting an aging population, yet they face lower life expectancy and poorer health outcomes due to socioeconomic disparities. A one-size-fits-all approach would exacerbate inequities.
The Role of Māori and Pacific Expertise
Māori and Pacific expertise must be central to the design and implementation of any population strategy, with Te Tiriti o Waitangi as the foundational principle. This requires access to a high-quality data system, which is currently at risk due to shifts in census methods and cuts to social science research funding. The degradation of demographic expertise and evidence, particularly for Māori and Pacific peoples, is a concern that must be addressed.
The Political Landscape and the Risk of Missed Opportunities
With an election approaching, there is a risk that serious demographic debate will be overshadowed by political point-scoring on immigration and ethnic relations. This would be a missed opportunity for Aotearoa, as a thoughtful and inclusive population strategy is essential for the country's future. The call for a population commission is a step in the right direction, but it must be supported by a commitment to engage with diverse communities and address the underlying issues driving demographic changes.
Conclusion
Aotearoa's demographic challenges require a thoughtful and nuanced approach. While the Koi Tū report offers a compelling case for a national population strategy, it is essential to consider the limits of policy intervention and the unique demographic circumstances of Māori and Pacific communities. By embracing diversity as a design principle and engaging with expert voices, Aotearoa can develop a strategy that adapts to inevitable changes while working towards a more equitable future.
