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


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


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%


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


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.


Manufacturing – 20 This sector is sampled utilizing

SALISES’ database of manufacturers and exporters.


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



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.


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.


• 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.
