Why birth rates may be falling – and what It costs to raise a bean
First published in the Jersey Evening Post 2025-08-29
In Jersey, we often speak of children born on the Island as “beans” – with pride, affection, and a deep sense of place. But in recent years, fewer beans are being born. The birth rate in 2024 hit its lowest point in modern memory, and early figures for 2025 suggest the decline is continuing.
Much of the public conversation has focused on high housing costs, long working hours, and the general unaffordability of raising a family. But one crucial ingredient is often missing: a clear-eyed estimate of what it actually costs to raise a child to adulthood in Jersey. This article offers a ballpark figure, based on reasonable modelling assumptions, to inform and provoke a more grounded public conversation.
What Do We Mean by “Average”?
Let’s begin with our “base case.” We model an average Jersey family with one child, both parents in work, living in rented or mortgaged accommodation, and using the public health system. The child attends States schools, with no private education fees. Early years childcare is paid for, with support from the Nursery Education Fund and any other government subsidies. The family receives relevant tax reliefs.
This base case reflects the experience of many middle-income families – neither affluent enough to avoid cost pressures, nor poor enough to qualify for full income support. And it’s in this squeezed middle where much of Jersey’s demographic shift is playing out.
- Direct Costs to Age 18 (2025 Prices)
🧒 Early Years (0–4)
This is often the most expensive stage of all.
- Childcare (nursery + wraparound): Approx. £12,000/year
- Less: Nursery Education Fund (up to £4,680/year)
- Net childcare costs: ~£32,000 over four years
- Other costs (food, clothing, equipment): ~£6,000
- Subtotal: £38,000
🧒 Primary Years (5–11)
Education is free, but out-of-pocket expenses persist.
- Uniforms, school meals, activities: ~£1,500/year
- Holiday care / after-school clubs: ~£3,000/year
- Subtotal (7 years): £31,500
🧒 Secondary Years (12–18)
Costs rise again in teenage years.
- Uniform, tech, transport, school trips: ~£2,000/year
- Food, clothing, social life, enrichment: ~£3,000/year
- Subtotal (7 years): £35,000
🏡 Housing Cost Premium
Many families need to rent or buy larger homes once children arrive.
- Additional cost (2-bed to 3-bed rental): ~£800/month
- Over 18 years: ~£173,000
- This estimate is conservative and assumes moderate inflation.
Total Estimated Direct Out-of-Pocket Cost:
£38,000 (early) + £31,500 (primary) + £35,000 (secondary) + £173,000 (housing)
= £277,500
This figure does not include private tuition, international trips, or high-cost hobbies — just the basics needed to raise a child in Jersey today.
- Opportunity Cost of Lost Income
For many families, particularly mothers, the cost of a child is not just what you spend – it’s what you don’t earn. Taking a year’s maternity leave with reduced pay, or working part-time during the early years, can have significant long-term effects on income and pension contributions.
Let’s assume one parent reduces working hours for five years (e.g. from full- to part-time), losing around £15,000/year in net income. That’s an opportunity cost of £75,000 over five years – not including lost career progression or pension effects.
While some parents do return to full-time work with minimal financial impact, many do not. For dual-income households, especially those earning just above income support thresholds, this opportunity cost can tip the balance in family planning decisions.
- Government Reliefs and Offsets
Jersey’s tax and benefit system does offer partial mitigation:
- Child Allowance (if eligible): up to £3,000/year
- Nursery Education Fund: up to 20 hours/week for 38 weeks (value up to £4,680)
- Income Tax child reliefs (for single earners or lower-income households)
- Limited targeted support through Income Support
However, these measures are patchy, income-dependent, and rarely sufficient to fully offset the combined direct and opportunity costs. Many middle-income families fall between the cracks – not qualifying for help, yet struggling to cope.
What’s the Lifetime Return?
If a child grows up in Jersey and enters continuous employment from age 18 to 70, what might they contribute in return?
Let’s use Jersey’s median earnings of £39,520/year (as of 2024). Assuming real earnings growth of 1% and income tax at 20%, that’s a rough estimate of:
- £250,000–£300,000 in lifetime tax revenue (excluding Social Security contributions)
Add to that:
- Consumption tax (GST), property taxes, and indirect contributions to the economy through spending, volunteering, caregiving, and cultural life.
In short, raising a child is not only a private commitment. It’s an investment in the Island’s future — financially, socially, and culturally.
Why This Matters Now
Jersey is not unique in experiencing a falling birth rate, but we are particularly exposed to its consequences. Our small size, ageing population, and reliance on a finite pool of working-age taxpayers make demographic decline more dangerous here than in many larger jurisdictions.
The Island Plan and Strategic Priorities speak of “supporting families” — but without a clearer understanding of the real costs involved, policy risks becoming aspirational rather than effective. If we want more beans — more children born here, raised here, and contributing to Island life — we need to understand both the cost and the value of raising them.
A Debate Worth Having
This article does not offer prescriptions. But it does offer a starting point. If the total cost of raising a child in Jersey — even with government support — may exceed £350,000 once lost earnings are included, then we should not be surprised when young Islanders hesitate to start families.
Equally, if each bean contributes far more over a lifetime — in taxes, care, and community — than they cost to raise, we should ask what more we can do to make parenthood feel possible again.
In the end, it’s not just about the maths. It’s about what kind of Island we want to be.
