Victimization Survey Methodology

Business Victimization Survey Refining of businesses for consideration  Focus on those businesses that had the greatest probability of being victimized.  Make the assumption that those businesses that have greater exposure to the public, will have greater levels of victimization.

Business Victimization Survey – distribution of sectors

Business Victimization Survey Next stage is to decide which businesses are to be excluded – Exclude those businesses that don’t fit the specified criteria. This leaves us with the following sampling frame Construction, mining, quarrying Wholesale and retail trade Hospitality (hotels, bars, nightclubs) Finance, insurance, real estate and business services General Services

Business Victimization Survey – revised distribution of sectors

Business Victimization Survey From this distribution, the various sector shares for sampling are as follows:  Mining and Quarrying/Construction: 10.51%  Manufacturing: 11.43%  Wholesale and Retail Trade and General Services: 62.45%  Tourism (Hotels, Restaurants, Bars and Nightclubs): 14.49%  Commercial Bank Branches: 1.12%

Business Victimization Survey Given this distribution, and the sampling limit of 300, the initial sample sizes were as follows:  Mining, quarrying and construction – 32  Manufacturing – 34  Wholesale, Retail Trade and General Services – 187  Tourism (Nightclubs, Bars, Hotels, Restaurants) – 44  Commercial bank Branches - 3

Business Victimization Survey Three issues affected the distribution that we ended up with. 1. The high level of heterogeneity expected in the wholesale and retail trade and general services 2. The high level of homogeneity expected in manufacturing businesses on the same estate 3. The need to have a greater spread of commercial banks

Business Victimization Survey – final distribution  Mining, quarrying and construction – 20  Manufacturing – 20  Wholesale, Retail Trade and general Services- 120  Tourism (Hotels, Restaurants, Bars, Nightclubs) - 40  Commercial Bank Branches - 10

Business Victimization Survey – sampling frame  Mining and Construction – 20  This sector was sampled utilizing entries in the Telephone Directory under the headings Building Contractors and Road Building Contractors.

Business Victimization Survey – sampling frame  Manufacturing – 20  This sector is sampled utilizing SALISES’ database of manufacturers and exporters.

Business Victimization Survey – sampling frame  Wholesale and Retail Trade and General Services – 210  Given the spread of these entities across the country, it is important to investigate the geographical distribution. Utilizing the Barbados Statistical Service’s Database we segmented the country into five regions with the following distribution observed

Business Victimization Survey – sampling frame

Of the 210 to be sampled from retail/general service and wholesale: – The total number of retailers/general service providers to be sampled is 200. These selected at random and stratified according to geographical location. – The wholesale element to be included is under the heading Wholesale- Grocers. Ten (10) enterprises selected at random from the Telephone Directory.

Business Victimization Survey – sampling frame  Tourism (restaurants, bars, nightclubs, hotels) – 40  From the Telephone Directory there were 136 hotels and guest houses, 233 restaurants and 72 bars and nightclubs. However, a large overlap was seen with restaurants and bars and nightclubs. The distribution for sampling was determined as 10 hotels and guest houses and 30 restaurants/bars/nightclubs.

Business Victimization Survey – sampling frame Commercial Bank Branches – 10 – Commercial Bank Branches (including the multi-branch Barbados Public Workers Cooperative Credit Union) were sampled are as follows: RBTT-1 Butterfield-1 Bank of Nova Scotia-2 First Caribbean-2 Barbados National Bank-2 Barbados Public Workers Cooperative Credit Union-1 Royal Bank of Canada-2

Business Victimization Survey – procedure  Managers/owners  Face-to-face interviews  Enumerators given two lists  For businesses with multiple locations – concern is with specific branch

Household Victimization Survey  Multi-stage sample design based on data from the 2000 population & housing census.  Stage one: The 11 parishes grouped into 4 homogenous strata. Then a set of enumeration districts (Eds) selected with the probability based on population size.  Stage two: 25 households from each ED sampled. Total of 1,125 households. (1.4% of total household population)

Household Victimization Survey – strata and allotment of EDs

Household Victimization Survey – canvassing  Upon arrival, the enumerator first locates the boundary of the ED with the help of an ED map.  He/she will then survey the ED to familiarize himself/herself with the area to be covered  The enumerator will then proceed to conduct the survey from the starting point shown on the ED map.

Household Victimization Survey – canvassing  The enumerator will canvass the area, moving to the left and enumerating all buildings found on the left hand side of the road/boundary in a sequential order. The specific households to be sampled will be based on the population of the ED and the interval computed to make the systematic selection.
