STATION AND PASSENGER TRENDS: 1950-PRESENT
The growth of the underground is minimal, not many stations come about due to passenger decline.
Passenger decline on the underground is caused by the notion of “open road”. The number of people using vehicles increased bringing a slight decline in ridership for the next 20 years.
This was a traumatic decade for London as the inner city was depleting. This resulted in a drop in jobs causing unemployment to rise. As a result construction of stations was stagnant and ridership heavily declined.
Following the trauma of the 70s, the growth of the underground picked up, also resuming the upwards trend in passenger journeys.
After the prosperous period, infrastructure as well as ridership remains fairly constant for a period of time.
During this period there was a large increase in line growth, including the extension of the Jubilee line to Stratford. It proved to be very successful due to the large increase in ridership following its completion, as it serviced a whole new area of London.
In more recent history the increase in stations appears to be minimal and well considered. Ridership has been much greater than the addition of minor stations can explain for. But we can note that the outward growth in population results in more people needing to commute using the tube.
PRESENT ZONING AND LAND VALUE
A present day map to show the zoning of the London Underground fares geographically. Most opaque central layer being zone one, and most expensive decreasing outward.
Graphs showing the land value above the most congested tube lines through each zone. Highlighted area of each graph being the land value as the line passes through zone one. It is notable that this is the most valuable area of London.
This map shows the most expensive places to buy property in London. The lighter colour being the most expensive.
All the above maps support the idea of the London city center remaining in the same demographic area while the greater city spreads away from it.
