How many people are there age 13-24 in the UK and in the US?

We researched population demographic data, to determine the size of the population in the United States, and the United Kingdom, between the ages of thirteen and twenty-four.

UNITED STATES

Census data did not directly indicate the total number of individuals aged 13-24 in the United States. To extrapolate the correct total population within the indicated age range, we identified a research report indicating 25 million 12-17 year olds, and 30.8 million 18-24 year olds in the U.S. as of July 1, 2016. The total of these two age categories is 55.8 million. To correctly calculate individuals aged 13-24, we needed to remove the total number of individuals aged 12 years old from our previous total of 55.8 million. According to census data, there were 4,139,596 individuals 12 years of age, or 1.28%, of the total U.S. population, which was 323,405,935, according to our source data, adjusted to the date of July 1, 2016. To finalize our calculation we then subtracted 4,139,596 from our previously calculated total of 12-24 year olds, or 55.8 million, to arrive at a total of 51,660,404 individuals aged 13-24 in the United States, as of July 1, 2016.

UNITED KINGDOM

In the United Kingdom, population data is published by the Office of National Statistics (ONS). The ONS provides downloadable population statistics on its website. We downloaded the available dataset for mid-2016. We extracted age and population data from the report section titled "Table 3. Population estimates for the UK, by sex and single year of age, Mid-1971 to Mid-2016 ALL PERSONS" as follows, each data point consisting of age and population, respectively: 13: 703,991, 14: 693,304, 15: 713,265, 16: 732,627, 17: 757,787, 18: 771,671, 19: 803,577, 20: 813,795, 21: 820,603, 22: 855,164, 23: 866,757, 24: 897,432. We then calculated the sum total of all data points. The number of individuals aged 13-24 residing in the United Kingdom was 9,429,973, as of mid-2016, the most recent year data was available within the specified age range.

CONCLUSION

We researched the total number of individuals aged 13-24 residing in the United States and the United Kingdom. Our findings were based on the most recent data available.

How many people are there age 13-24 in London, New York City, and Los Angeles?

Each of the requested figures have been triangulated using the most recent publicly available data. According to these calculations, there are approximately 1,184,608 to 1,674,972 people aged 13 to 24 in London, 1,100,670 to 1,567,163 in New York City, and 1,136,692 in Los Angeles. Due to the limited availability of statistics, these figures serve as an estimate.

LONDON

Unfortunately, no pre-compiled data could be identified. As such, a figure has been calculated using publicly available data. The most recent census in London was conducted in 2010, the next due in 2021. The requested demographic of people aged 13 to 24 does not fully align with the age groups studied in the 2010 census. Therefore, I have calculated two values to allow for overlapping age groups. Moreover, population statistics for 2016 have been identified in order to formulate a more up-to-date response. Below you will find a full description of these calculations.

In 2010, the following resident figures have been identified:
• 10 to 14 years old = 456,865.
• 15 years old = 93,599.
• 16 to 17 years old = 186,626.
• 18 to 19 years old = 191,434.
• 20 to 24 years old = 629,972.
• All age groups = 8,173,941.

Next, percentages can be calculated using the total resident figure and individual age groups:
• Including the 10 to 14 age group, there are a total of 1,558,496 residents (aged 10 to 24). Using the total residency figure of 8,173,941, this equates to 19.06% of the population.
• Excluding the 10 to 14 age group, there are a total of 1,101,631 residents (aged 15 to 24). Using the total residency figure of 8,173,941, this equates to 13.48% of the population.

In 2016 the total population of London amounted to 8,787,892. Using these percentages an aged 13 to 24 residency value for 2016 can be calculated:
• In 2011, 19.06% of the total population was 10 to 24 years old. Therefore, 19.06% of 8,787,892 can be calculated to 1,674,972.22.
• In 2011, 13.48% of the population was 15 to 24 years old. In turn, 13.48% of 8,787,892 is 1,184,607.84.

Rounding these figures, this gives a final range of 1,184,608 to 1,674,972 people.

NEW YORK CITY

Similarly, no pre-compiled data could be found at this time. As such, a figure has been calculated using all publicly available data. A 2016 census of New York City has been identified as the most recent statistical information. The specified demographic of people aged 13 to 24 does not fully align with the age groups studied in the census, however, a range of values have been calculated for your convenience. Below you will find a full description of these calculations.

In 2016, resident figures can be identified by age group and gender. As these statistics are classified by gender, two figures were extrapolated for each age group:
• 10 to 14 years old = 236,832 + 229,661 = 466,493.
• 15 to 19 years old = 241,442 + 238,486 = 479,928.
• 20 to 24 years old = 303,071 + 317,671 = 620,742.

By totaling these figures, estimates can be provided:
• Including the 10 to 14 age group, there are a total of 1,567,163 residents (aged 10 to 24).
• Excluding the 10 to 14 age group, there are a total of 1,100,670 residents (aged 15 to 24).

Finally, this gives a final range of 1,100,670 to 1,567,163 people.

LOS ANGELES

Regrettably, despite a thorough search, no pre-compiled data could be located. A figure has been triangulated using publicly available data. In 2016 there was a complete census of the population in Los Angeles. The requested demographic of people aged 13 to 24 does not fully align with the age groups studied in the census. In this case, the age groups are not separated fully. Despite an additional search, no further statistics could be located to aid in this triangulation. Below you will find a full description of these calculations.

In 2016, the following resident figures have been identified:
• 10 to 19 years old = 458,832.
• 20 to 29 years old = 677,860.

Totaling these figures, this gives a final estimate of 1,136,692 people (aged 10 to 29). Due to the limited availability of data, this figure represents a high estimate of the desire 13 to 24 age demographic.

CONCLUSION

To sum it up, despite an exhaustive search no pre-compiled data could be found. Figures for each of the requested demographics have been calculated using data extrapolated from the most recent public census. In regard to Los Angeles, it may be of note that an exact figure is available behind a pay wall.

How many people aged 13-24 purchase online clothing in London, New York City, and Los Angeles?

There are millions of young people in the cities of London, New York and Los Angeles and there is no information available that tells us how many of them purchase online clothing. There does not appear to be any studies publicly available that give us insight into the number of percentage of that age group that buys their clothes from e-commerce sites. However, there is research indicating they spend a sizable percentage of their money on clothing, and their online buying habits are increasing.

Populations

There are approximately 1,160,700 people aged 13-24 in Greater London, 2,999,717 in New York City, and more than 2,173,032 in the Los Angeles metro area (649,165 in the city of Los Angeles proper).

The U.K.

In the U.K. students (ages 16-24) are estimated to contribute £20 billion ($28.4 billion) to the economy each year. London has about 12.5% of the population, so that would be $3.55 billion. In general, "Approximately 87% of U.K. consumers have bought at least one product online in the last 12 months ... According to data from the Office for National Statistics, online sales increased by 21.3% during 2016 and should reach 30% by 2017’s second half." After electronics and digital media, the most common purchase sector is the fashion industry, with clothes and footwear accounting for almost one-third of online purchases."

The U.S.

In the United States, average spending may range from $1,646 per year for teen males, to $9,825 for items both bought by and for teens to $27,010 for those ages 19 to 29. BusinessInsider states that teen spending on clothing has decreased to 19% of their total spending in 2017. Millennials (18-24) make 67% of their purchases online. Doing some rough calculations (67% of purchase x $1,646 total spend x 19% of purchases are clothing) brings us to at least $210 per person per year spent online on clothing by 13-24 year old Americans. And the actual figure is likely higher given I used the lowest figure in the calculation.

Conclusion

To wrap it all up, we can’t say how many people aged 13-24 purchase online clothing in London, New York City, and Los Angeles, but using the above dollar figure and population estimates, we can gauge the market to be at least $630 million in New York, $456 million in Los Angeles, and $244 million in London.
