Map categories:

All the maps provided here applied the mesoframe methodology to represent information thematically. Four categories of maps are provided namely:

  • the base mesozone dataset updated in 2011,
  • the main economic sectors,
  • employment for each main economic centre, and
  • total population

 

Users with access to geospatial software can also download and utilise the GIS data layers. GIS data is provided in ESRI shapefile format. Where possible, relevant metadata descriptions have also been added to the map.

 

1. MAP 1: Base mesozone dataset (without any attributes)

 

Description:

This shows the extent of the mesozones along with the latest district municipal- and provincial boundaries. This version represents the updated 2011 version of the mesozones. This version incorporates the latest boundary revisions as on 1 December 2011 as published by the Municipal Demarcation Board of South Africa.

2. Main Economic Sector maps

For each of the 9 main (SIC level 1) economic sectors (except SIC 5: Construction) the appropriate ancillary or proxy data was identified in order to execute the dasymetric process. The sectors are:

  • Agriculture, forestry and fishing (SIC1)
  • Mining and quarrying (SIC2)
  • Manufacturing (SIC3)
  • Electricity, Gas and Water supply (SIC4)
  • Wholesale and retail trade; Repair of motor vehicles, motor cycles and personal and household goods; Hotels and restaurants (SIC6)
  • Transport, Storage and Communication (SIC7)
  • Financial Intermediation, Insurance, Real Estate, and Business Services (SIC8)
  • Community Social and Personal Services, as well as Government Services (SIC9&10)

Economic data was supplied by Quantec for the year 2009. For each sector Gross Value Added (GVA) was used as it is a measure of the value of goods and services produced in an area, industry or sector of an economy. (See also)

The source for the SIC category descriptions used here is ‘Statistical Papers, Series M, No. 4, Rev. 3, Department of International Economic and Social Affairs, Statistical Office of the United Nations, New York, 1990’ provided by Statistics South Africa.

 

Map 2.1 – Gross Value Added Total (2009)

The concept of Gross Geographic Value Added (GVA) – is used as a basis for making estimates of regional economic activity – is broadly similar to what is more generally known as Gross Geographic Product (GGP). In essence:

GVA (factor cost) =   Compensation of employees + Gross Operating Surplus

As noted, the highest intensity areas (with more than R 1 billion GVA per mesozone) are indicated by a range of purple and blue colours. These generally comprise major towns or metropolitan nodes, but some are also the locations of major power stations or industrial areas (such as the Secunda complex). The second colour band (the three red classes) typically includes medium-sized towns and significant non-metropolitan mining areas.

Map 2.4 - GVA - Manufacturing (SIC3)

Description

Manufacturing is defined as the physical or chemical transformation of materials or compounds into new products, whether the work is performed by power-driven machines or by hand, whether it is done in a factory or in the worker’s home and whether the products are sold wholesale or retail. The assembly of products from component parts is considered to be Manufacturing, except in cases where the activity is appropriately classified under Construction. *

Map 2.6 - GVA - Wholesale and retail trade; Repair of motor vehicles, motor cycles and personal and household goods; Hotels and restaurants (SIC6)

 

This division includes the resale (sale without transformation) of new and used goods to retailers, to industrial, commercial, institutional or professional users; or to other wholesalers; or acting as agents or brokers in buying merchandise for or selling merchandise to such persons or firms. The principal types of businesses included are merchant wholesalers, i.e. wholesalers who take title to the goods they sell, such as wholesale merchants or jobbers, industrial distributors, exporters, importers, and co-operative buying associations, sales branches (but not retail stores) which are maintained by manufacturing or mining units apart from their plants or mines for the purpose of marketing their products and which do not merely take orders to be filled by direct shipments from the plants or mines. Also included are merchandise and commodity brokers, commission merchants and agents, buyers and co-operative associations engaged in the marketing of farm products. Wholesalers frequently physically, sort and grade goods in large lots, break bulk, repack, redistribute in smaller lots, e.g. pharmaceuticals, store, refrigerate, deliver and install goods, engage in sales promotion for their customers and design labels. *

3.   Employment per sector

 

To calculate estimates of employment per sector the following data sources was utilised.

  • Quantec 2009 employment figures at the Local Municipal (LM) level
  • Quantec 2009 GVA figures per sector (nine sectors) for each LM (this was also used and proxy data)

A standard process was followed to determine the employment totals for each of the following sectors:

Primary sector:

  • Agriculture, forestry and fishing
  • Mining and quarrying

 

Secondary sector:

  • Manufacturing
  • Electricity, gas and water

 

Tertiary sector:

  • Wholesale and retail trade, catering and accommodation
  • Transport, storage and communication
  • Finance, insurance, real estate and business services
  • Community, social and personal services; as well as general government

 

The GVA for each of these sectors was used as the proxy variable for employment. This was done by following the following steps:

  1. Obtain the GVA for the sector in question at the LM level;
  2. Obtain the employment figures per LM;
  3. Calculate the ratio between GVA and employment, in essence the production value per individual for the sector;
  4. Apply this ratio (as calculated above) to the GVA figures per mesozone, i.e. the data that was prepared in a previous process which yielded the GVA production per mesozone for each of the sectors as mentioned earlier.
  5. The result is an approximation of the number of employed people per sector in each mesozone.

 

Note: This employment figure is indicative of employment at place of work and not place of residence as the GVA figures per mesozone are based on whether there is activity for that sector present in the specific mesozone, e.g. a mine or factory.

4.            Demographic data

An approach based on dasymetric mapping principles was used in order to calculate population distribution. The Spot Building Count (produced by the CSIR and ESKOM in 2008) is a geo-referenced building frame developed using Spot 5 satellite imagery. The inventory concerned contains all classifiable building structures within the borders of South Africa. According to this classification, each point inherited a weight representing the potential contribution (household size) of the point in question. The following factors were taken into consideration in order to undertake the classification:

  • residential areas which have not changed since the last census;
  • new urban growth areas;
  • informal areas;
  • commercial and industrial areas;
  • rural areas (agricultural, nature reserves and other sparsely populated areas).

 

The analysis results were produced for the whole of South Africa. The results of this process were tested against detailed population updates of the City of Cape Town and eThekwini. The intraclass correlation coefficient (ICC) per census sub-place was calculated. The intraclass correlation coefficient is a descriptive statistic that can be used when quantitative measurements are made on units that are organized into groups. It describes how strongly units in the same group resemble each other. The groups in this instance would be each sub-place with two measures indicating the total population. It differs from Pearson correlation in that it shows not only if there is a correlation in trend but also intra (internal) correlation between the values obtained (Mans, 2011). The results were an ICC of:

  • 0.907 for City of Cape Town
  • 0.899 for eThekwini

In other words, the values produced using the SBC-data frame method is consistent with that of the control totals (total population as derived by the two cities respectively).

5.            Settlement Typology

 

Development

The typology was developed as part of the National Spatial Trends Overview project (2008-2009) commissioned by the South African Cities Network, The Presidency and former DPLG to inform Cabinet discussions on urban development policy aspects and the process of developing the Urban Development Framework.  The typology was developed as through an interactive technical and consultative process, overseen by an expert reference group (will provide more detail on technical process) and widely consulted and presented within development planning, and government policy and planning units.

 

The Purpose and key challenges of settlement typology:

1.  To highlight the value & role (more nuanced understanding) of the social and economic role of the interconnected range/network of settlements within the country

2. To highlight the importance of the functional urban and rural concentrations (settlements within traditional urban and rural contexts)

3.   To understand the regional importance of different functional settlement areas, and for that purpose:

  • consider the functional linkages between so-called former white towns and functionally linked former ‘black towns’, as well as towns with large dependent settlements with little economic activity on the borders of former homeland areas
  • develop a functional settlement description that moves beyond a urban/rural divide
  • avoid a mere focus on cities/towns in terms of a hierarchy of population size or economic activity (largely skewed by the SA apartheid legacy)

 

Identification of the various types of settlements was done by using the basis of the Functional Urban and Rural typology and the GAP platform.

City Region

Population >1million, Government & Economic Services Index>7

Cities

Population >400000, Government & Economic Services Index 2-5

Regional Service Centres 1

Population 300000 -500000, Government & Economic Services Index 1-2

Population 100000 - 300000, Government & Economic Services Index >0.3

Regional Service Centres 3

Population 60000 - 100000, Government & Economic Services Index >0.25

Service Town

Significant role in hinterland (Service Index 0.065-0.25) and Population mostly >20 000

Local and Niche Towns

Service role in immediate surroundings (Service Index 0.001-0.065). Population size varies widely

Rural Nodes in High Density Settlement Areas

Meso Zones with >100 people/square km OR more than 10 people/square km PLUS Economic activity in service sector - identified as areas within high density settlement areas, with highest levels of access to household income

High density settlement areas

Meso Zones with >100 people/square km OR more than 10 people/square km PLUS Economic activity in service sector

Rest of South Africa

Less densely populated areas, Sparsely populated areas, mountainous, national parks
