Kingmakers created an index score for each metric for each state. In each metric, the top state based on the raw data was given 1 point and the bottom state was given 37 points. States between these were indexed proportionally. For the overall rankings, Kingmakers created an average of the seven category rankings, and then ranked the outcome. We chose this method for the overall ranking so that it would not be skewed by large differences in scores at a metric level.

The Data

In order to select metrics for the project, we consulted experts in each of the categories for guidance. These are the criteria we used in choosing metrics:
  • Metrics that measure citizen outcomes in a state were favoured over inputs or outputs. For example, we selected the percentage of state residents who had finished primary school education or higher instead of the amount spent on education per capita or the number of students enrolled at state schools.
  • The set of metrics within each category should work together to provide an overview of that category.
  • Standardized data needed to be available across all or most states.
The data behind the rankings were sourced from

Kingmakers.com Calculations

Population

The data for the population for the states was acquired from the National Population Commission and National Bureau of Statistics. We got the total population for each of the states of the years 2006, 2008, 2010 and 2011. We then calculated the compound average growth rate (CAGR) from 2006 to 2011 and used that to extrapolate the population count for the years 2012 to 2015.

V(t0): start value, V(tn): finish value, tn – t0: number of years.

The same method was used for calculating for the values for the male and female population as well as the distribution across age groups.

There are a few limitations to using CAGR to forecast metrics and they include:

  1. CAGR calculates the smooth average of growth over a period, it ignores volatility and implies that the growth during that time was steady. Yet, this is never actually the case. As such, we cannot take CAGR at face value.
  2. CAGR is mainly a historic measurement and , no matter how steady the growth of a metric has been over a period of time we cannot safely assume that the growth will continue at the same rate during the following year or years, as other factors may come into play and affect that rate of growth.
  3. Lastly, CAGR has a problem with representation. Say for instance a metric’s CAGR could be an impressive 50% over the past three years. However, due to poor or negative growth in the two years preceding those three years, the CAGR over the past five years could come down to more modest 2.73%.
However, still we adopt a culture of collecting and collating data more periodically, CAGR is one of the tools are our disposal to make calculated guesses to fill in the void for the years no data was collected.

Assisted Delivery

The data used for assisted delivery rate was got from the Demographic and Health Surveys (DHS) Program. There were surveys were carried out in the following years: 1999, 2003, 2008 and 2013.

The results from 1999 were excluded from our calculations as we considered the data was too old. The 2003 and 2008 surveys only contained results for the six geopolitical zones in which the states were located, while only the 2013 survey contained results for both the geopolitical zones and the individual states.

We calculated the CAGR from each of the geopolitical zones from 2008 to 2013 and 2003 to 2013.

Since we had only data at state level from 2013, we used the CAGR from 2008 to 2013 to retrogressively get the values for 2012, 2011 and 2010.

V0 = V1 x (100%-CAGR(2008, 2013))

V0: Retrogressive value to be calculated, V1: value from the succeeding year, CAGR(2008, 2013): compound annual growth between 2008 and 2013 for the geopolitical zone in which the state is located.

For example:

Abuja FCT
2013 Assisted Delivery Rate (V1) = 84.6%
CAGR(2008, 2013) for North Central Zone = 2.1%

2012 Assisted Delivery Rate (V0) = 84.6 x (100% - 2.1%) = 82.8

To get the values for the years succeeding years from 2013 to 2015, we got the value for the by multiplying the value of the preceding year with the following formula

V0 = V1 + (V1 x CAGR(2003, 2013))

V0: Progressive value to be calculated, V1: value from the preceding year, CAGR(2003, 2013): compound annual growth between 2003 and 2013 for the geopolitical zone in which the state is located.

By using the longer period of 2003 to 2013 for the CAGR, we were looking to have a much better representation of forecasting what the value might be as we do not have any data for the years succeeding 2013.

Same method used for all ther other paramters except Adult Life Expectancy, Education Quality, Incidence of Poverty, Unemployment Rate & Work Seggreation


Cooking Fuel

We got the data for the type of cooking fuel used by Households in Nigeria from the Nigerian Bureau of Statistics which had surveys from 2007 and 2011. The CAGR for each individual states was calculated and then used to forecast possible values for 2010 and 2012 – 2015. The drawbacks of using CAGR as a method as forecasting has already been discussed and its limitation in the area of proper representation was particularly pronounced as in some case, the metric measurement forecasted presented as a percentage of the household using solid fuels for cooking was more than 100 percent. These values had to be adjusted to the maximum possible value.

We did this technique for the data for access to sanitary facilities, improved drinking water and improved refuse collection.


Adult Life Expectancy

Looking the national data for infant mortality rates and the life expectancy at birth since 1980, we noticed that was a negative correlation between the two metrics. As infant mortality rates drop, life expectancy at birth increased. The data was used to develop a linear regression equation which had the following statistics

The infant mortality rates were calculated using data from the DHS Program and the applied to the linear regression equation to get the adult life expectancy.

Life Expectancy = 59.87237 – ( 0.111 x 'Infant Mortality Rate' )


Education Quality

WAEC Results were used to judge the education quality of each state. For the 2015 WAEC Results, while we got the rankings for all the states, we were unable to get the pass rate for two thirds of the states. The states were Abia (1) - 63.94%, Anambra (2) - 61.18%, Edo (3) - 61.05%, Lagos (6) - 48.02%, Ekiti (11) - 41.97%, Ogun (19) - 32.91%, Kano (24) - 25.44%, Borno (25) - 24.65%, Oyo (26) - 21.03%, Niger (27) - 19.66%, Adamawa (28) - 18.08%, Osun (29) - 18.03% and Yobe (37) - 4.37%

We used linear regression equations, similar to the one below, to get an approximate value for the missing pass rates based on their ranks after listing the states according to their ranks.

y = a + bx

y: the projected pass rate for state, a: the y-intercept, b: the slope and x: the state rank.

The y-intercept and slope were recalculated using the reported pass rates before the missing information, and those just after.

Poverty Rate

To come up with the rankings for our poverty we decided to use the multidimensional approach which takes into account several factors that constitute poor people’s experience of deprivation – such as poor health, lack of education, inadequate living standard, lack of income (as one of several factors considered), disempowerment, poor quality of work and threat from violence.

A multidimensional measure can incorporate a range of indicators to capture the complexity of poverty and better inform policies to relieve it. Different indicators can be chosen appropriate to the society and situation.

For the purpose of the 2016 rankings we used the indicators and the weights as stated below. The indicators were chosen to reflect lack of education, poor health and inadequate living standards, in some cases taking only indicators as relates to the female population only, which are all directly under the purview of the state governments. The weightings were similar to those used by Oxford Poverty & Human Development Initiative (OPHI) and the United Nations Development Programme in drawing up their up poverty reports.

  • LACK OF EDUCATION INDICATORS
    • Educational Attainment: This took into account the proportion of the female population who had not completed primary school education. (17 percent)
    • School Attendance: The average of the proportion of school aged female children that were not attending both primary and secondary school. (17 percent)
  • POOR HEALTH INDICATORS
    • Child Mortality Rate: The proportion of female children who died within 5 years from birth. (17 percent)
    • Child Nutrition: The proportion of female children who had developed stunted growth. (17 percent)
  • INADEQUATE LIVING STANDARDS
    • Use of Solid Fuel: The proportion of the population that use solid fuels to cook. (8 percent)
    • Unimproved Sanitation Facilities: Proportion of population with no access to improved sanitation facilities. (8 percent)
    • Unimproved Drinking Water: Proportion of population with no access to improved drinking water sources. (8 percent)
    • Unimproved Refuse Collection: Proportion of population with no access to improved refuse collection. (8 percent)

The sum of the indicators gave us the proportion of the population that were likely to be facing multidimensional poverty in each of the states.


Unemployment Rate

The International Labour Organisation’s (ILO) recommendation for calculating unemployment is cover people who are: out of work, want a job, have actively sought work in the previous four weeks and are available to start work within the next fortnight; or out of work and have accepted a job that they are waiting to start in the next fortnight. The calculation should exclude those within the labour force who do not have a job and are also currently not seeking employment.

This is the method that the National Bureau of Statistics currently uses for calculating unemployment on a national level. The previous simply looked at those who were currently unemployed in the labour regardless of their job seeking status and expressed that as a percentage of the total labour force.

Looking at the national data, we found that there was a correlation between the percentage of people currently not employed regardless of their job seeking status and the unemployment rate which uses the recommendations stipulated by the ILO. We developed a linear regression equation which gives an approximate value for the unemployment rate using the percentage of people not actively participating in the labour force as its input.

We took data from the DHS Program to get the percentage of people not actively involved in the labour force by adding the number of people who were not currently employed and those who had not been employed in the last 12 months of the survey. Using the same technique as stipulated earlier for calculating the adult literacy, we forecasted the non-participatory labour rates for all the states from 2011 to 2015, and using those values as the input for our linear regression equation, we derived the unemployment rates.

UR = ( ( NCE + NE12 ) x 0.743947 ) - 11.1697

UR: Unemployment rate, NCE: Percentage of labour force not currently employed, NE12: Percentage of labour force not employed in the last 12 months.

Work Seggregation

This was calculated by looking at the data obtained by the Demographic and Health Surveys (DHS) Program in 2013 where currently employed respondents (male & female) were asked about their occupation and the percent of women employed in professional, technical, or managerial positions were determined as well as other categories included those who worked in agriculture, skilled manual jobs and in unskilled manual jobs.

The CAGR for each individual states was calculated for each occupation group and then used to forecast possible values for 2011, 2012 and 2014 and 2015. We used the same technique as that for Assisted Delivery as explained above.

To calculate the work segregation for the individual states for the years 2011 to 2015, we used the Duncan Segregation Index using the formula shown below:

Where n is the number of job categories, which was 4, and mi and fi represent the percent of males and females working in a job category respectively.

I is the segregation index and when When I = 0, it implies that there is no segregation in any job category. In other words, Mi = Fi. When I = 1, it implies that there is complete segregation in all job categories. This can be seen since when Mi >0, the Fi = 0 and vice versa.
