Mount Claremont
Wealth here is held outright rather than borrowed. At 44.8% of households owning with no mortgage, against 37.9% still paying one, Mount Claremont reads as established money, and the data backs it: household income sits in the 96.3rd percentile nationally and the suburb scores decile 10 on all four SEIFA indexes, the top advantage tier on every measure. University qualifications reach 62.7%, which is 32.6 points above the national figure, while the median age of 45 runs 5.0 years older than national. The $638,000 median house price looks modest for this profile only because it is estimated from rent, with the real draw being a detached, low-density setting where 77.6% of dwellings are separate houses.

Buyers come for space, not density. Separate houses make up 77.6% of stock against just 4.0% apartments, and 53.1% of dwellings carry four or more bedrooms, far above the typical metro mix. The $638,000 median house price (estimated from 2025 rent) is the entry signal, though the four-bedroom dominance means most listings sit well above that line. Monthly mortgage repayments average $3,033, producing a mortgage-to-income ratio of 24.7%, comfortably below the 30% stress threshold despite the premium postcode, because incomes in the 96.3rd percentile absorb the cost. Three-bedroom homes add another 29.1% of stock, so the market is built for families rather than first-home downsizers, who would find little two-bedroom supply at 13.5%.

For Investors
The investment case here is thin on yield and built on scarcity. Only 17.3% of residents rent, the smallest tenant pool you typically see in a premium suburb, and weekly rent of $420 against the $638,000 median implies a gross yield near 3.4%, modest once holding costs are counted. The 6.2% vacancy rate is workable but not tight, and zero development applications were lodged in the past 12 months, so new rental supply is not arriving. Demand support comes almost entirely from overseas migration, the primary driver at 140 net arrivals a year versus just 17 from internal movement. Rent grew 19.0% over the decade, which means the return profile leans on capital preservation and rent escalation rather than the high turnover or yield an income investor would want.

Demographics
The resident base skews older and highly educated. Median age of 45 runs 5.0 years above national, and the trajectory is aging: the senior share rose 4.0 points while the working-age share fell 2.4 points over the decade. Overseas-born residents reach 33.8%, which is 12.2 points above national, yet ancestry stays strongly Anglo-Celtic, led by English (2,017), Scottish (627) and Irish (577), with Chinese (359) the largest non-European group. University qualifications at 62.7% sit 32.6 points above national, among the highest anywhere. The top non-English languages are Mandarin (65 speakers) and Cantonese (22), a small international layer over an English-speaking majority. Average household size of 2.7 is 0.2 above national, consistent with the family-heavy, four-bedroom housing stock.

Tenure
Tenure tilts heavily toward outright ownership: 44.8% own with no mortgage, 37.9% carry one and only 17.3% rent. Outright owners outnumbering mortgage holders points to long-held, debt-free wealth rather than a churn of recent buyers, and the low renter share keeps the market owner-occupier driven. The stock is 77.6% separate houses and 18.4% semi-detached, leaving apartments at just 4.0%, which sustains detached-house values through limited density. Four-plus bedroom homes dominate at 53.1%, with three-bedroom at 29.1%. The $638,000 median house price is estimated from 2025 rent rather than sales, so it understates true detached values. Mortgage-to-income at 24.7% and rent-to-income at 14.8% both sit well below the 30% stress threshold, a sign that housing costs are easily carried at 96.3rd-percentile incomes.

Economy & Employment
The local workforce concentrates in high-skill sectors. Healthcare leads at 20.8% (398 workers), Professional/Tech follows at 18.0% (345) and Education at 12.8% (245), with Mining a notable 11.3% (216) reflecting WA's resource economy. By occupation, Professionals (1,070) and Managers (485) make up the bulk of jobs, which aligns with the decile 10 IEO score for education and occupation. Unemployment is low at 3.9% and the full-time employment rate is 56.9%. Participation reads 59.2%, below what the income would suggest, because the aging profile leaves 1,381 residents not in the labour force. Real incomes grew 20.8% over the decade. All four SEIFA indexes score decile 10, with IRSAD at 1,150 and IEO at 1,171, confirming top-tier advantage on every measure rather than a single anomaly.

Transport to Work
Daily life leans on the car: 79.5% drive, while only 10.5% take public transport and 4.3% walk or cycle, below the active-transport share of denser inner suburbs. The suburb earns decile 10 on IRSAD, the top advantage tier nationally, and decile 10 on IRSD for relative disadvantage, meaning very few residents face deprivation. Volunteering runs at a high 29.1%, and only 3.8% (184 people) need daily assistance despite the older median age of 45. No schools are recorded inside the 4.43 km2 boundary in this dataset, so families rely on institutions in neighbouring suburbs, a practical trade-off for the low-density, detached-housing layout at 1,129 residents per km2.

Population Forecast

(+135 people/yr)
EstablishedGrowth is steady but slow, classifying Mount Claremont as an established suburb. Annual population growth registers 1.27%, around 135 persons a year, and overseas migration is the primary driver at 140 net arrivals annually against just 17 from internal movement. The profile is aging, with the senior share up 4.0 points and the working-age share down 2.4 points over the decade, so expansion comes from new arrivals rather than a younger resident base. Affordability improved from 47.7% in 2011 to 38.2% in 2021 as real incomes rose 20.8%. The gentrification stage reads early signs with a score of 40, modest because the suburb already sits at decile 10 advantage, leaving little room to climb further up the ladder.

Frequently Asked Questions
Is Mount Claremont a good suburb to live in?
Mount Claremont ranks decile 10 on all four SEIFA indexes, the top advantage tier nationally, with household income in the 96.3rd percentile. University qualifications reach 62.7%, which is 32.6 points above national. The main trade-offs are car reliance, with 79.5% driving, and no schools recorded inside the suburb boundary.
What is the median house price in Mount Claremont?
The median house price is $638,000, estimated from 2025 rent rather than sales, so it likely understates true detached values where 53.1% of homes have four or more bedrooms. Weekly rent averages $420 and monthly mortgage repayments run about $3,033, a mortgage-to-income ratio of 24.7%.
What schools are in Mount Claremont?

Is Mount Claremont safe?
Detailed crime statistics are not available for Mount Claremont in this dataset. As an indirect indicator, the suburb scores decile 10 on the IRSD index of relative disadvantage, the highest tier, and only 3.8% of its 4,999 residents need daily assistance, both consistent with a low-disadvantage area.
Is Mount Claremont good for property investment?
Rent of $420 a week against a $638,000 median gives a gross yield near 3.4%, modest after costs, and only 17.3% of residents rent. The 6.2% vacancy rate is workable, but zero development applications in 12 months means little new supply, so returns lean on capital growth over yield.

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
