Two-or-more-person households in Saitama City have average annual income of about ¥10.36 million, but the published figure for households in their 50s stands out at about ¥20.25 million. Urawa and Omiya help explain why Saitama City can have relatively high household income, but the 50s figure should not be treated as "normal" for Saitama City without considering sampling and one-off income.
Annual income of two-or-more-person households in Saitama City by age of household head (2019)
| Age of household head | Annual income (¥1,000) | Approx. ¥ million |
|---|---|---|
| Average, all ages | 10,364 | About ¥10.36m |
| 40–49 | 10,146 | About ¥10.15m |
| 50–59 | 20,245 | About ¥20.25m |
| 60–69 | 9,037 | About ¥9.04m |
| 70–79 | 7,936 | About ¥7.94m |
Only the 50s jump to roughly twice the overall average
Households headed by people aged 40–49 have annual income of ¥10.146 million, those aged 60–69 ¥9.037 million, and those aged 70–79 ¥7.936 million. The figure for ages 50–59 alone is ¥20.245 million, more than ¥10 million away from both neighboring age groups.
It is valid to report this as a published figure, but it is not a smooth age-income curve. A small city-by-age sample may have included high-income households, retirement payments, business income, or other large receipts. It is safer not to use this one point as a definitive picture of ordinary households in their 50s.
Urawa's higher-income residential areas and Omiya's urban functions support the average, but the outlier is a separate issue
Urawa and Minami wards are home to many large-company managers and professionals who commute to Tokyo, while Omiya has employment tied to commerce, administration, and its role as a major Shinkansen transport hub. These two urban functions are important background factors behind Saitama City's relatively high household income among major Kanto cities.
But the strength of Urawa and Omiya alone cannot justify generalizing the ¥20.25 million figure for households in their 50s. The National Survey of Family Income, Consumption and Wealth is a sample survey, and values can fluctuate more in narrowly defined city-by-age groups. The part that can reasonably be linked to local background should be kept separate from sampling uncertainty.
How to read these figures
These statistics cover annual income for two-or-more-person households and may include business income, pensions, dividends, retirement payments, and other sources in addition to wages. City-by-age estimates can also be sensitive to sample size, causing unusually large values in particular age groups.
For Saitama City, it is therefore appropriate to begin with the all-age average of ¥10.364 million and treat the unusually high age-specific figure as supplementary information. The 50–59 value requires particular care in city comparisons and time-series comparisons.
Summary: Saitama City is relatively high-income, but the ¥20.25 million figure for the 50s should be treated as a reference value
The citywide average of about ¥10.36 million is consistent with the economic strength of Urawa and Omiya, but the published ¥20.25 million figure for households in their 50s should be treated as a possible outlier. It should be read alongside neighboring age groups and not used as a household-finance benchmark.
- Overall average: about ¥10.36 million
- 40s: about ¥10.15 million; 60s: about ¥9.04 million
- 50s alone stand out at about ¥20.25 million
- Do not confuse the city's higher-income structure with sampling variation
