Population Pyramid of Yokohama City (as of October 1, 2000)

1 Total population

The total population of Yokohama City is 3,426,651.

The total population (confirmed number) of Yokohama City as of October 1 according to the 2000 census was 3,426,651, an increase of 119,515, or 3.6%, compared to the previous survey seven years. The population growth rate rose 0.9 points from 2.7% in 1997, the lowest post-war period of 2.7% in 1997, except for 1995 and 22 due to the effects of the war.
Compared to 1920 (422,938 people), 80 years ago when the first survey was conducted, it was about 8.1 times that of 1950 (951,189 people) 50 years ago.
The population density is 7,839 per square meter, an increase of 252 compared to the previous survey.
The population size of the city is the second largest after 8,134,688 in the Tokyo metropolitan area (calculated as one city) out of 672 cities nationwide, 2.7% of the total population (126,925,843), and Kanagawa Prefecture's total population (8,489,974) occupies 40.4%. (Tables 1-1, 1-2, and Figure 1)

Figure 1 Changes in the Population of Yokohama City

2 Population by Administrative District

The population growth rate in Tsuzuki Ward   is 32.8%, and the trend is increasing in central wards.

By administrative district, Kohoku Ward was the largest at 294,305 (8.6% of the city population), followed by Aoba Ward with 270,044 (7.9%) and Tsurumi Ward with 254,103 (7.4%). Meanwhile, the smallest number was 78,320 in Nishi Ward (2.3%).
The population growth rate in Tsuzuki Ward   is particularly high at 32.8%, and the population is rapidly increasing due to moving into New Town. Aoba Ward accounted for 8.5%, Naka Ward accounted for 6.7%, and Midori Ward accounted for 6.5%, and the population growth rate increased mainly in northern cities.
Sakae Ward decreased 3.7%, Isogo Ward decreased 3,553, or 2.1%, and Konan Ward decreased 98, or 0.0%, respectively.
Compared to 2012 years, the population growth rate in Nishi Ward (-1.6% → 3.4%), Naka Ward (0.2% → 6.7%) and Minami Ward (-1.1% → 1.4%) show a tendency to return to urban centers.
In terms of population density, Minami Ward was the highest at 15,459/km2, roughly twice the city average (7,839/km2) and Nishi Ward (11,157/km2) and Konan Ward (11,180/km2) are above 10,000/km2. (Table 2)

3 Population by gender

The population ratio is 102.6

Looking at the population by gender, there are 1,735,392 men, 1,691,259 women, and 44,133 more men. The population ratio (the number of men per 100 women) is 102.6, which is 6.8 points higher than the national average of 95.8 points, but in 1995 it decreased by 1.4 points from 105.3 in two years, and in 12 years it has decreased by 1.3 points, and recently the ratio of women has increased.
In terms of population ratio, Naka Ward was the highest at 110.6, followed by Tsurumi Ward at 109.3, Kanagawa Ward at 106.9 and Kohoku Ward at 105.9. On the other hand, the lowest is 97.9 in Sakae Ward, where the number of women in five wards exceeds the number of men. (Table 2)

4 Population by age
（１） Age 3 Separated Population
Looking at the population by age, the young population under the age of 15 is 474,656 (13.9% of the total population), the working-age population aged 15 to 64 is 2,463,151 (71.9%), and the elderly population aged 65 and over is 477,053 (13.9%).

The elderly population exceeds the young population to 13.9% of the total population.

Looking at the changes in the population by age group after the war, the elderly population was only 32,582 in 1950, but then rapidly increased at a rate of more than 25%, reaching 477,053 in 2000, It has increased 14.6 times over the last 50 years. Compared to the fact that the total population was only 3.6 times between 1950 and 2000, it can be seen how remarkable the increase in the elderly population after the war was. As a result, the elderly population exceeded the young population for the first time since the start of the survey. In addition, the ratio of the total population to the total population was only 3.4% in 1950, but continued to expand with each survey, exceeding 11.0% for the first time in the previous survey, and 2.9 points in 2000 compared to 7 years It is 13.9%, and the aging is progressing at an accelerating rate.

The progress of declining birthrate is slowing

The young population continued to increase from 312,659 in 1950, and exceeded 600,000 in 50 years due to the rise in the birth rate caused by the second baby boom. After that, it peaked at 666,549 in 1955, and decreased by 76,408 (12.2%) from 1960 to 2002, and decreased by 60,086 (10.9%) from 2 to 7 years, and decreased by more than 10% from 2 to 7 years. 6 years. The ratio of the total population in 2000 was 13.9%, which is shrinking to the same level as the elderly population.

The working-age population begins to shrink

The working-age population continued to increase consistently from 605,886 in 1950, but remained a slight increase of 15,543 (0.6%) from 1995 to 2012. The ratio of the total population to the total population has been around 70% since 1965, the highest since the survey started at 74.0% in 1995, but has decreased by 2.1 points in 2012. (Table 4-1, Figure 4)

（２） Population pyramid

The population pyramid is a "two-story building with a long eaves"

As in the whole country, the form of the population pyramid of Motoichi has swelling in the first (51-53 years old) and the second (26-29 years old) baby boom period, but the swelling is large, and the second baby boom period is larger than the first "two-story long with a long eaves" type.

1) Includes age "unknown".
2) The total number in 1940 includes foreign residents. Figures by age do not match the total number because only inland people.

Figure 4 Changes in the Percentage of Population by Age (3 Category) (1919 to 2012)

（３） Age composition index

The old age index rose significantly to 100.5.

Looking at the age composition index of Motoichi, the young population index (the number of young populations for 100 working-age population) continued to decline from 51.6 in 1950, and became 31.6 in 40 years. . It temporarily rose to 36.4 in 1950 after the second baby boom, but has declined again since 1955, reaching 19.3 in 2000.
On the other hand, the elderly population index (the number of elderly populations compared to 100 working-age population) was 5 to 6 units in the 1940s and 19.4, the highest value since the start of the survey.
The old age index (the number of elderly populations for 100 young people), which is an indicator of the degree of aging of the population, has been changing from 10 to 20 from 1950 to 45 after the war, but since 1975, it has risen rapidly due to a decline in the young population and an increase in the elderly population, and in 2000, it has increased to 2.30 from 2.
The average age is 40.1 years old, up 1.9 years from 38.2 years in 7 years. (Table 4-2)

Note) Child population index = population under 15 years old / population between 15 and 64 years old x 100
Elderly population index = population aged 65 and over / population aged 15 to 64 x 100
Dependent population index = (population under 15 years old + population over 65 years old) / population between 15 and 64 years old x 100
Geriatric index = population aged 65 and over / population under 15 x 100
Average age = age (each age) x population by age / total population +0.5

（４） Age structure by administrative district

As the population ages throughout the city, the highest percentage of the elderly population is 18.5% in Nishi Ward.

Looking at the proportion of the elderly population by administrative district, Nishi Ward was the highest at 18.5%, followed by Naka Ward at 18.0%, Minami Ward at 17.6%, and Isogo Ward at 15.7%. The lowest figure was 8.1% in Tsuzuki Ward  , followed by 9.7% in Aoba Ward and 12.4% in Kohoku Ward and Midori Ward.
The youngest population is 19.9% in Tsuzuki Ward  , followed by 16.4% in Aoba Ward, 15.2% in Izumi Ward, and 14.9% in Midori Ward and Seya Ward. The lowest percentage was Nishi Ward 10.6%, followed by 11.4% in Naka Ward and 11.8% in Kanagawa Ward and Minami Ward.
In this way, in Motoichi, the proportion of the elderly population is high in the central ward, and the proportion of the young population is high in the northern ward. In addition, the proportion of the elderly population has increased from five years ago in all wards, and the elderly population has grown from four wards (Kanagawa Ward, Nishi Ward, Naka Ward and Minami Ward) to ten wards.
The age composition index shows a similar trend, with the old age index at 173.6 in Nishi Ward up to over 90 in most wards. On the other hand, Tsuzuki Ward   is 40.5 and Aoba Ward is 59.5, which is extremely low in the two northern wards. (Table 4-3)

１） Including age "unknown".
２） See Table 4-2 for the calculation method of each age composition index.

5 Population of Concentrated Areas (DIDs)

DID population accounts for 97.4% of total population and 78.9% of total city area.

The population of the densely populated area, which represents the actual situation of the urban area, was 3,338,859, an increase of 128,817, or 4.0%, compared to 1995 (3,210,042). Accounted for 97.4% of the total population, an increase of 0.3 percentage points from 97.1% in 2017. By administrative district, the population of the four wards of Tsurumi Ward, Nishi Ward, Naka Ward and Minami Ward resides in the concentrated areas.
On the other hand, the area of the population-intensive area is 345.0 km2, accounting for 78.9% of the entire city. In addition, the population density of the population concentration area is 9,678 people / km2, indicating the overcrowding situation of Motoichi. (Table 5)

＊The population-intensive district (DID = Densely Inhabited district) is an expansion of the city area due to the merger of municipalities under the Municipal Merger Promotion Act of 1953 and the New Municipal Construction Promotion Act of 1956, and the establishment of a new city. The regional chapters by city and county are not necessarily specified in the national census.
Until the 1990 census, it was set based on the survey area in charge of the census investigator, but since 1995, it has been based on the basic unit area.
Population-intensive districts are areas where basic unit districts with high population density (in principle, population density is 4,000 or more per 1 km2) are adjacent within the boundaries of municipalities, and the population is more than 5,000.

6 marital status

55.5% of women aged between 25 and 29 are unmarried.

The marital status of the population aged 15 and over in 2000 by gender shows that among males aged 15 and over (1,484,181), 521,674 unmarried persons (35.1%) and 869,399 (58.6%) and 40,40,404 (divorce) death of spouse (divorce (death of spouse) On the other hand, divorce, death of spouse, 871,672 (59.9%) and death of spouse (140,533) (death of spouse, 9.7%) and 5,533 (9.7%) and divorcedivorce (9.7%).
Looking at the percentage of marital status by age group, the unmarriage rate is on the rise in most age groups for both men and women, and in recent years, it has risen significantly in young age groups. In particular, the unmarried rate of women is 24.3% for those aged 25 to 29 compared to 1980, 20 years ago. → 55.5%, 9.8% for those aged 30 to 34. → It has risen significantly to 26.6%, which is considered to be one of the factors behind the decline in the birth rate.
In contrast to the unmarried rate, marital rate has been declining among young people, and compared to 1980, 74.6% for women aged 25 to 29. → 42.8% and 71.4% for men aged 30 to 34. → This was down to 52.8%.
The death of spouse rate has risen as the age increases, but the recent growth in life expectancy has led to a decline in all age groups. Compared to 1980, for example, 12.5% of men between the ages of 70 and 74. → 8.2% and women 57.2% → This has declined to 33.3%.
The divorce rate is high among middle-aged and older people, with men aged between 55 and 60 (4.9%) and women aged between 50 and 54 (6.4%). Also, looking at trends in the divorce rate, there is a tendency for each age group to rise. (Tables 6, Figure 6)

Overview of the 2000 Census

1 Purpose of the Survey
The census is the most basic statistical survey of the country conducted to clarify the actual situation of Japan's population, households, industrial structure, etc., and to obtain basic data on various administrative measures in the national and local governments. . The survey has been conducted almost every five years since 1920, and the 2000 census is the 17th time.

2. Date of Survey
The 2000 census was conducted as of midnight on October 1, 2000 (hereinafter referred to as "at the time of the survey").

3 Areas of Survey
