I think the real problem is the disparity across uk in
costs of living
actual services ie not every town has train station, rural areas poor bus services.
when dd1 was little all the buses had steps no low level on my route.
First bus drivers seem to hate kids and find the experience stressful so avoid.
To get to nearest 2 job centres would be 2buses costing £4 or 1 bus costing £6.
My gps is now 45min walk and not on a bus route anywhere near me they relocated to new premises so when joined they were handy.
schools -seems odd london dont pay but outside london people pay vast amounts.
Then take into account devolved areas
wales/scotland.
random councils giving free travel, swimming, free school dinners to all.
Its fair to say
income varies depending on area.
as does housing costs.
but cost of raising a child can be different in each area too.
I know someone with 2 in seniors paying £1200 a year in buses she cant drive them as has to get younger 2primary and a lot of schools are not walking distance.
where as say for example you live in issslington and yours kids get free travel , free school dinners and theres more ammenties things are not overly far from each other.
Last few years has seen
shortage of school places men parents doing 2 schools which costs them extra childcare/travel.
closure of sure start centres, medical centres, libaries mean people forced to travel further not everyone has the basics on their doorstep.
one could argue that this generation of parents have harder time as
high housing costs.
travel costs
childcare costs are huge not everyone lives near families for free childcare.
tuition fees.
rising energy costs, cost petrol running a car these days is high.
