Population growth is a global issue that contributes to the changes in the distribution and concentration of population. Population growth affects the sustainable development of an area from both a social and spatial point of view. To relate the global problem to a local issue, this research investigates one of the Malaysian government policies addressed as the New Economic Policy (NEP) because the policy may be linked to long-term spatial demographic changes in Peninsular Malaysia, particularly in the distribution of people. Back in 1970, the policy was implemented after an unwanted incident on 13 May 1969. Its goals were to eradicate poverty regardless of race and to restructure society by eliminating the identification of race with economic functions. To measure the successfulness of the policy, two indicators that were derived from the goals are the long-term spatial changes of both racial and occupational segregation. The magnitude for both segregations was calculated using the Entropy Index (H). The values were then carried forward to evaluate the relationship between these two variables. The final analysis was conducted using the Local Bivariate Relationships application of a Geographic Information System (GIS) tool. The outputs then reflect the two sustainable goals that are, (i) reduced inequalities, and (ii) sustainable cities and communities in Peninsular Malaysia.

The implementation of the New Economic Policy (NEP) had taken place in peninsular Malaysia for 20 years . It was formulated as a social re-engineering in the aftermath of the 13th of May 1969 Incident. The NEP was "as simple as two eyes" because it targeted to eradicate poverty and at the same time to restructure society in order to eliminate the identification of race with economic function. The objectives reflected that the NEP was focusing on demographic aspects, particularly targeted at eyeing the division of races based on economic function. In conjunction with that, this article aims to study the changes in racial segregation in peninsular Malaysia from 1980 until 2010. To strengthen the findings, this article introduces spatial elements to geo-visualize the long-term changes in the spatial pattern of racial segregation in peninsular Malaysia. In terms of statistical analysis, racial segregation was calculated by using the Entropy Index. In the course of spatial analysis, the results were then being mapped by applying Geographic Information Systems (GIS) according to each district in peninsular Malaysia. Generally, the results divulge that from the year 1980 to 2010, districts in peninsular Malaysia experienced medium segregation of H value between 0.6144-0.7339. However, in detail, the value varied across each district. It was observed that the majority of districts on the East Coast experienced a high degree of racial segregation compared to the majority of districts on the West Coast.

Over time, the relation between criminal acts with drug abuse cases has been discussed pedantically. From social and spatial points of view, this paper aims to determine the hot spot areas of burglary cases in the Northeast Penang Island District and Kuching District. The gained results of burglary cases are then being correlated with the presence of drug abuse cases. Both study areas came with location coordinates of the incident based on police stations boundaries and police station sector boundaries from the year 2015. The type of analysis used for this research is Optimized Hot Spot Analysis. Results for burglary cases of both areas are divided into two (2) which are daytime and nighttime. The spatial analysis revealed that there are five (5) sectors identified as hot spots for the Northeast Penang Island District which involve Jelutong Police Station boundary and Ayer Itam Police Station boundary, while none of the areas identified as hot spot areas in Kuching District.
