Language matters in Hong Kong’s birth rate debate, not just money

Hong Kong's fertility debate often focuses on financial measures such as increased baby bonuses, tax breaks, housing assistance, and affordable childcare. These economic strategies are crucial as they alleviate some immediate barriers to having children. However, another, less apparent factor that may influence fertility decisions stems from the language spoken daily.

Consider the difference in how English and Chinese languages handle the concept of time. In English, present and future time are marked grammatically, such as "Yesterday it rained. Now it is raining. Tomorrow it will rain." In contrast, Chinese languages do not change the verb form to indicate future time. This difference, discovered by behavioral economist Keith Chen, suggests that speakers of languages with weak or no future-time marking tend to save more, plan better, and invest more in long-term health.

The reason is that when the future is not marked grammatically, it feels closer and more present, making its burdens feel immediate as well. This can encourage individuals to save more and plan for the future, but it can also create anxiety and hesitation, especially for long-term commitments like raising a child. Chen's research implies that the grammatical structure of a language might influence how vividly people imagine the future and how much weight they assign to that imagined future in significant life decisions.

In Hong Kong, where Cantonese is spoken by around 88% of the population while English is used by about 4.6%, many residents are bilingual or multilingual, often switching between languages within the same conversation. This linguistic flexibility could mean that the way a person perceives the future might be influenced by the language they are using at any given moment.

While Chen's findings do not directly address fertility, they provide a logical projection that future obligations might feel more immediate for speakers of languages with weak future-time marking, potentially making the commitment of raising a child seem heavier. This linguistic perspective adds a new dimension to fertility policy discussions.

Economic measures such as baby bonuses and housing support remain essential, but incorporating language structure into policy evaluation could reveal additional insights. For instance, examining how language use in family planning discussions affects couples' perceptions and hopes could offer valuable perspectives. Encouraging couples to articulate their family planning goals in different languages, perhaps through exercises like visualizing future generations, might help policymakers understand how future visions are shaped by language.

Ultimately, while affordability is a critical factor in fertility decisions, the way people perceive and conceptualize the future—through the lens of their language—could also play a significant role.
