Abstract
Issues related to the modifiable areal unit problem are well-understood within geography. Though these issues are acknowledged in the spatial crime analysis literature, there is little research that assesses their impact. In fact, much of the cited spatial crime analysis literature that investigates the impact of modified areal units suggests that there is no problem—there is, however, an alternative literature. In this paper, we employ a new area-based spatial point pattern test to investigate the impact of modified areal units on crime patterns. We are able to show that despite the appearance of similarity in a (spatial) regression context, smaller units of analysis do show a high degree of variation within the larger units they are nested. Though this result in and of itself is not new, we also quantify how much spatial heterogeneity is present. This quantification is undertaken using multiple crime classifications and in a cross-national comparison.

We define spatial heterogeneity being present when a large spatial unit of analysis has smaller spatial units of analysis within it that do not all exhibit the same properties.
- 2.
There is also the issue of missing data because of underreporting of crime and/or systemic biases in reporting crime. This may or may not have spatial implications, but we are unaware of any research that addresses this issue.

Prior to the 2001 census, these census boundaries were called enumeration areas.
- 5.
The street network in Vancouver recognizes to which side of the street a point is geocoded. If that particular street is a boundary for a spatial unit, the point is assigned to the census unit on the appropriate side of the street in the spatial join.

There are two general forms of spatial point pattern tests: area-based and distance based. See Andresen (2009) for a discussion of their respective benefits and limitations.

An 85% sample is based on the minimum acceptable hit rate to maintain spatial patterns, determined by Ratcliffe (2004). Maintaining the spatial pattern of the complete data set is important so we used this as a benchmark for sampling. An 85% sample was for the purposes of generating as much variability as possible while maintaining the original spatial pattern. Also note that “replacement” in this context refers to subsequent samples; any one point may only be sampled once per iteration in this procedure to mimic Ratcliffe (2004).
- 8.
The program written to perform the test uses double precision that has at least 14 decimal points when dealing with numbers less than unity. The smallest number that we have to deal with in the current analysis (regardless of scale) is 0.000034553. This is well within the limits of double precision.

It should be noted that the role of local spatial analysis has been growing in interest in recent years (Lloyd 2011).
