We've used the territory manager tool in Prospex GIS to split the UK into north, south and east and west with equal population counts. A Geographical Information System GIS , is a tool for analysing, visualising, managing and presenting data that is related to a physical, geographical location.
That link to geography is the key difference between GIS and other data visualisation techniques. The UK Census what it is, how is it made, and how can it be used to help your organisation with demographic analysis. After almost 10 years of service, Google retired their Fusion Tables product at the end of This tool was very useful at visualising and sharing large amounts of tabular data - particularly amongst small and mid-sized businesses.
So what can we do to fill the gap left by this tool? The Beacon Dodsworth site uses cookies to improve your user experience and to provide analysis of how our site is used.

A brief history of the postcode How does the modern postcode system work? Postcodes, not just for post Alternatives to postcodes: the geography of government.
More about postcodes: Postcode-to-postcode journey planning Postcodes give us a great key around which to plan travel, but for fleet or salesforce planning the calculations can be staggering. The geography of government How administrative geography has developed, how it works and how it compares to postcode geography. The power of postcode sectors Grouping postcodes together into areas is a powerful geographic analysis tool but isn't as easy as you might think.
A brief history of the humble postcode: When and why were postcodes introduced? After Mail volumes grow. A postcode system was needed to facilitate automated sorting. Early s: The Royal Mail starts a mechanisation program to introduce reliable mechanical sorting. Sorting machines needed the address to be machine-readable, so a code system was developed from the Norwich trials.
Norwich is the last place to be re-coded. How does the modern UK postcode system work? District: One or two alphanumeric characters subdividing the area. Inward code Sector: 5: One numeric character subdividing the district.
Unit: QW: Two alpha characters showing a group of buildings, a street, part of a street or a single delivery point. Largest size IV, Inverness 6, square miles. Average size square miles. Smallest population ZE, Shetland 22, people.
Largest population B, Birmingham 2 million people. Average population , Smallest number of districts in an area ZE, Shetland 3. Largest number of districts in an area BT, Belfast Average number of districts in an area Largest size is IV27, 1, square miles. Average size 33 square miles. Smallest population UB11, West Drayton Largest population CR 0, Croydon , Average population 23, Smallest size EC3A 1, London, less than 0. Largest size IV27 4, Lairg, Sutherland, 1, square miles.

Demographic profiling: Postcode boundaries provide a convenient way to tie people into manageable groups with similar lifestyles and outlooks to form the building blocks of geodemographic analysis. Postcode mapping and geographic analysis: Although postcodes focus on addresses, their aggregated groupings and boundaries provide an ideal building block for geographic analysis. Journey and logistics planning: Postcodes are a far more accessible reference than coordinates or longitude and latitude making them ideal for setting departure and destination points in navigation tools.

TimeTravel: the latest update We look at the latest update to TimeTravel, our dataset of drive times and distances between any postcode sector or district. Cycle to work day Each year for cycletoworkday we take a look at cycling statistics across the country and try to map that data and find interesting trends. Each full Postcode contains an average of 15 delivery points and each postal delivery takes place in two stages.
When a letter is collected it is routed to a main sorting office identified within the first part of the Postcode, the Outward Code. Postcodes operate at four levels.
The country is divided Areas denoted by the first two letters of the Outward half of the Postcode. The average number of delivery points within each Area is , Each Area is subdivided into District Postcodes.
The District is denoted by the number or numbers that complete the first half of the Postcode or Outward Code. There are just over 2, Postcode Districts, an average of 21 Districts within each Area, and the average number of delivery points within each District is 8, Each District is further segmented down into Sectors 9, in total which are denoted by the first number of the second part of the Postcode.
This half of the Postcode is called the Inward Code. The fourth and final level of the Postcode pinpoints a group of houses or addresses. Some organisations are allocated a unique Postcode to ensure the segregation of large deliveries of mail to a single address. If an organisation receives, on average, fifty or more items of mail a day, then a large user Postcode may be allocated.
There are times when it becomes necessary for Royal Mail to make changes to postal addresses on a large scale. There are a number of reasons these changes are undertaken. For example, new building developments, both residential and business e. Because of the geographical nature of the Postcode system it is necessary to consider the wider area and allocate new Postcode segmentation.
The Postcode is part of a coding system created by the Royal Mail. The Postcodes are an abbreviated form of address, and enable a set of Delivery Points normally letter boxes for addresses to be grouped. This is why Royal Mail prefers the Postcode to be separate and on the last line of an address. The format and rules concerning Postcode layout, in particular which letters can or cannot be used, stem from the fact that certain characters or combinations of characters could be confused e.
A Postcode is a combination of letters and numbers which defines four different levels of a geographic unit. Each Postcode consists of two parts, called the Outward Code e.
