Do you often look around and wonder where all the children have come from?

(Not the ones in your own home, hopefully you can account for them.)

But in your neighbourhood. Is it abundant with fresh little babies, choc-a-block with toddlers and teaming with exhausted mothers desperate for a caffeine fix?

Do you have to push past the prams at the local shops to get down the aisle?

Does it make you wonder where they sprung from?

On average in Australia we each have 1.8 babies but some spots, such as Melbourne’s Point Cook and Cranbourne are their own little baby belts.

In Melbourne almost 20,000 babies were born in the year to June 2014 within just six Melbourne growth municipalities – Wyndham, Whittlesea, Melton, Hume, Casey and Cardinia.

The Age reports that within 20 years, it is expected almost 600 births will be recorded each week in a baby belt through Point Cook, Cranbourne and Doreen.

For residents in NSW new figures from the NSW Registry of Births, Deaths and Marriages show that state's baby hotspots with families in the south-west and west our biggest breeders.

In NSW our most fertile towns were Orange and Dubbo, both in the central west.

While the suburb of Blacktown had the most babies born in any town or suburb for the third year in a row.

Fairfax Media reports that rounding out the top ten are Auburn with 740 births, Bankstown with 682, Merrylands with 587, Orange had 550 births, Parramatta 534 births, Dubbo had 522, Liverpool 476, Guildford 473, Randwick had 467.

The figures are based on the mother's home address at the time of birth.

Births, Deaths and Marriages Registrar Amanda Ianna? said the same suburbs are featuring in the top 10 baby hotspots every year

"Clearly many parents believe the west is best when it comes to babies," she told The Sydney Morning Herald.

"Over the past decade, western Sydney has been driving the state's population growth as young families are drawn to affordable housing and employment opportunities."

Dr Nick Parr, associate professor in demography at Macquarie University told Fairfax Media birth rates were generally lower in areas with higher socio-economic status. "The areas towards the centre of Sydney, in the eastern suburbs, and on Sydney's north shore tend to have lower per-woman birth rates," he said.

Other states reflect the same pattern -  Brisbane's lower fertility areas are in central Brisbane either side of the river, while the higher fertility areas are in the north, south and islands. Melbourne's lower fertility rates are concentrated in the inner suburbs and middle suburbia to the east and south-east. according to the ABS.  The higher fertility rates are seen in the outer west, north and south-east.

In Adelaide, ABS statistics show that inner Adelaide and the beach-side suburbs from Brighton to Semaphore have lower fertility rates, while higher rates are in the outer northern and eastern areas.

Perth's lower fertility rates are found in the inner area bordered by Scarborough, Fremantle, Canning Vale and Maylands. The outer northern and southern areas have higher fertility rates.

Greater Darwin's lowest fertility rates are in Darwin City, followed by surrounding suburbs and eastwards to Howard Springs.

In Canberra there are lower fertility rates mostly in the inner north of Canberra, while most areas with higher rates are in the outer south and north. While in Hobart, Hobart and Sandy Bay, have lower fertility rates and the remaining greater Hobart area has higher fertility.

According to the ABS 91,000 babies were born in NSW in the last recorded statistical year 2014, 74 224 were born in Victoria, 63 066 in Queensland, 20 384 in South Australia and 35 403 in Western Australia.

Where you come from does influence the number of babies you have.

Women born in Lebanon who give birth in Australia have an average of 4.03 children each reports Fairfax Media, while mothers born in Laos have 3.4, 3.38 for Syrian-born mums, 3.26 for mothers born in Samoa and 3.02 for those born in Pakistan.

According to the ABS Victoria has the lowest total fertility rate of 1.73 while the Northern Territory the highest at 2.10.

The Blog "ID the population experts" have documented that the local government area with the highest fertility rate is Corrigin in WA, with only 930 residents and a birth rate of 4.76 children per woman the locals there really do have to elbow away the prams to get to the coffee.
