Abstract

Public housing in Singapore is governed by the Housing and Development board. HDB flats are home to over 80% Singaporeans and hence it is important for all the stake holders to understand the supply and price trends for public housing. This will greatly influence the planning in future.

Problem and motivation

The study aims at -

• Understanding the share of supply of resale public housing in 2015.
  
• Studying the distribution of resale prices with respect to important dimensions such as town and flat type.
  
• Compare the patterns for 2015 and first half of 2016.
  
• Note key observations and inferences through visual analytics. The goal is to note a minimum of 3 observations in each case.

Tools Used

Tableau version 10.0

Approaches

Data collection and cleaning:
The housing data for 2015 and 2016 is available at https://data.gov.sg .The data is clean and ready for analysis. It was necessary to format few fields and data types to be ready to use with the tool.
Understanding the data:
The various dimensions used in the data set needs to be recorded. This can be easily achieved with appropriate visualization tools. Then we make a note on the different parameters we wish to study and the suitable graphical representation for each case. For instance, Histograms and Box plots could be used to study the Distribution of continuous data types such as prices.
Analysis:
The data set is imported to the tool and Visual infographics are extracted for each case. With this we note our key observations and compare patterns.
