**SSASIM: POP . id**

Identifies set of population parameters specified on this row of table, so id value should be unique.

Valid values: 1 to 999999999 (nine digits), Integer

Source code: pop.h and pop.cpp

**SSASIM: POP . notes**

Describes specification of table row in free-form note.

Valid values: any ASCII text (Note: do not copy and paste from a word processor because of the possibility of embedded non-ASCII characters.)

Source code: notes are not read by the model

**SSASIM: POP . tfr0**

Specifies initial RUN.year_zero value of total fertility rate (tfr), which is one of model's stochastic variables whose future ultimate (or post-transition) values are determined by ASSUMP and child tables parameters (see above). Value of tfr0 is expressed as the natural logarithm of the average total number of children born per woman.

Valid values: any, Real

Source code: pop.h and pop.cpp

**SSASIM: POP . tfr_kink**

Specifies whether or not transition path from initial value of total fertility rate to its ultimate, post-transition values has a single kink (or bend) point or is linear (without a kink).

Valid values: T (=1) or F (=0) (for true or false), Logical

Source code: pop.h and pop.cpp

**SSASIM: POP . tfr_kvalue**

Specifies tfr kink point value if tfr_kink is true. Value of tfr_kvalue is expressed as the log of the average total number of children born per woman in the kink year. If kink point is assumed, the tfr transition path is a linear interpolation from its initial year value to kink point value in every scenario. Scenario variation in transition path is restricted to years after tfr_kyear (see below), or after tfr_byear (if tfr_bend is true; see below), as tfr values are interpolated between tfr_kvalue (or tfr_bvalue) and the ultimate value of tfr, which is generated using ASSUMP and child tables parameters. Value is read only if tfr_kink is true.

Valid values: any, Real

Source code: pop.h and pop.cpp

**SSASIM: POP . tfr_kyear**

Specifies simulation year of tfr kink point value if tfr_kink is true. Value is read only if tfr_kink is true.

Specifies whether or not transition path from kink value of total fertility rate to its ultimate, post-transition values has a bend point or is linear (without a bend).

Valid values: T (=1) or F (=0) (for true or false), Logical [True value is allowed only if tfr_kink is true.]

Source code: capmrkt.h and capmrkt.cpp

**SSASIM: POP . tfr_bvalue**

Specifies tfr bend point value if tfr_bend is true. Value of tfr_bvalue is expressed as the natural logarithm of the decimal rate in the bend year. If bend point is assumed, the tfr transition path is a linear interpolation from its kink year value to bend point value in every scenario. Scenario variation in transition path is restricted to years after tfr_byear (see below) as tfr values are interpolated between tfr_bvalue and the ultimate value of tfr, which is generated using ASSUMP and child tables parameters. Value is read only if tfr_bend is true.

**SSASIM: POP . maxage_yng**

Specifies the maximum age assumed for the 'young' population.

Source code: pop.h and pop.cpp

**SSASIM: POP . use_mrfile**

Specifies whether or not to use a text file to provide mortality rate input when operating in CBA mode. When false (F), the normal logic of simulating mortality rates is used. The long-standing normal logic involves advancing RUN.year_zero mortality rates (see the HISTMR table) to subsequent years using the simulated aggregate mortality decline rate (see ASSUMP and child tables) combined with age/gender decline rate disaggregation information (see the MDR_GA table) is used. When true (T), the simulated mortality rates for years beyond RUN.year_zero are replaced with age/gender-specific mortality rates contained in a mortality rate text file, the name of which is specified in the POP.mrfilename field. See the documentation for that parameter for information about the format of the mortality rate input file. Notice that the phrase "for years beyond RUN.year_zero" implies that mortality rates in RUN.year_zero cannot be changed. NOTE: this parameter cannot be set to true when the PSG models are running under Unix-like operating systems like Mac OS X or Linux, and it cannot be set to true under Windows when operating in either the OLC, ESP, or RCS modes.

Valid values: T (=1) or F (=0) (for true or false), Logical

Source code: pop.h and pop.cpp

**SSASIM: POP . mrfilename**

Specifies name of text file containing the mortality rates to be used in the simulation. This parameter is read only if the value of POP.use_mrfile is true (T). If the input file is located in the same directory as the SSASIM database, then the mrfilename can be something as simple as, for example, mrf00001. If the input file is located in some other directory, specify the complete file name including the path (for example, \df\mr\basecase.txt). Each row of the input file must be structured exactly like rows in the .mrd output file (see NOTE below for more on the order of the rows). See the documentation for that file for row details. The .mrd file documentation can be obtained by executing a run with OUTPUT.mrd set equal to true (T) and then the output file in the RSF Toolkit from the Analyze menu. This capability has been designed so that the following will be true: (a) execute a run with OUTPUT.mrd=T and POP.use_mrfile=F and rename the resulting .mrd file; (b) change the run specification to OUTPUT.mrd=F and POP.use_mrfile=T (specifying POP.mrfilename as the renamed file) and execute the run; (c) compare the results of the first run from step (a) and the second run from step (b) to see that they are identical, apart from the possibility of minor rounding errors. NOTE: Although the row content in the mrfile input file must be exactly the same as in the .mrd output file, there is some flexibility on the ordering of the rows. Because the age range is 0..125 (with all mortality rates equal to one at age 125), there will be 252 rows for each calendar year. There must be one of these year blocks of 252 rows for each year in the simulation, and these year blocks must be in ascending order. Within a year block, the 252 rows can appear in any order. There must be a year block in the file for each of the RUN.num_years simulation years after RUN.year_zero.
